Curious what others are doing for backups..... I am about to take a sledgehammer to our current setup, and am curious what other people use and what backup strategies they employ. Cloud is not an option for our firm- our backups to tape can accommodate storage. Currently, we have a daily incremental backup, a weekly full backup that expires after 5 weeks and a monthly backup that never expires and is retained indefinitely. Currently, I have to schedule backups to run every Friday and then watch them all weekend because the backup software randomly marks our full backups as "superseded" (Just started this a month ago), and support was never good from this vendor. We have in-house Exchange, file servers, in-house SQL, an AD domain, and of course file servers. Almost our entire infrastructure is Hyper-V. Total amount of data is about 20TB. I'm more interested in strategies to safeguard the data than an actual product. Should I consider changing the weekly backups to only backing up data that has changed in the past 30 days, and have the monthly be all data? I'll take any suggestions or perspectives on the best way to do this.

Thanks!

A little history before I get crucified. Not my circus and not my monkeys.. I have a soft spot for the down trodden.  

Have a client that is still break\fix. 4 years ago I warned them I was no longer supporting Windows 2003r2. 2 years ago I warned them the server (Dell T300) could die. Offisite backup no… still using a 2011 version of Symantec Backup and backup had stopped working a year previously. However, I do have good System State backup
RAID 5 failed and hot spare flaked out, so had to send the drives out for data recovery. Data was recovered. All user folders and other files I put on a temp server so they could access them. Now the remaining problem is that they had a program that used SQL 2005. I have got SQL 2005 to load on 2008R2 and run as long as I put all the SQL service packs on it. The database will not restore. Their previous server was also the domain controller.

The software company said they would help, but wanted $15,000 upfront. The main reason this place was still on this system was that the company only supported server 2003R2 and SQL 2005 which was why they were still on it. The client was moving away from this company, but needs their accounting from the old software.

I have a client that has a T300 in the closet that was a domain controller with server 2003R2. It never got demoted because the access to old accounting software wouldn’t run on newer version of server. I got it and have it in the shop and it still runs 😊 So I was wondering if…

We have Always On set up currently by SQL 2016 both HA and DR in cloud platform. Now we plan to do Azure and cloud migration. We want to have Azure environment for HA and keep current cloud for DR. We will still use SQL 2016 enterprise How to do always-on between Azure and cloud platform? or other better solution like Log shipping and mirroring? I mean HA I always-on solution, and DR in log shipping

How to do mirroring AG in HA site to DR site? or can we mirror AG between HA site and DR site?

AWS - two questions pertaining to AWS, or hosted services.  First off, I am trying to get an idea if AWS is a cost effective hosting replacement solution for small business where in house they have anywhere from 1-6 servers, from a cost perspective.  I took a peak at some of the sizing tools for AWS, but not clear on how I would assess throughput, if all daily functions were moved to AWS.  Would you also move all infrastructure servers and clients would authenticate to DCs in the cloud?  I am not sold on this at all, but it makes absolute sense to know the pros and cons.  From a control and cost and security perspective it probably still makes more sense to go with in-house servers for small business, but need to confirm.


Secondly - what is the best way to get familiar with AWS, for small Windows environments, trying to see if it makes sense from a business continuity stand point. For example, currently using Veeam to replicate all VMs to another remote host, so if we lose site A, we can spin everything up within minutes.  Any thoughts on best way, to get a good understanding of AWS?

Thanks guys!!!

Hi,

We have been using a Seagate STDR5000200 external hard drive for backing up data from our local PCs and servers.

This drive was encrypted with Bitlocker.

While we were backing up data to this external hard drive, the PC, which this drive was plugged into, was turned off accidentally via a switch on the wall.

The next day, this drive was not recognised on the PC it was plugged into and after trying different Windows 10 and 7 PCs, I found that there could be a problem with this drive.

I used Seagates error checking tools and Seagate said from the result that this drive is not functioning properly.

Through the Disk Management on one of the Windows 10 PCs, I did "Rescan disks" and the corrupt drive was listed as "disk 6 unknown".

Right clicking on the disk 6 gave me the options; Initialize disk, Offline, Properties, help.

When I tried "initialising" the disk or clicking "properties", the Disk Management window freezes and eventually the disk 6 disappears from the PC.

Errors I received from this were : data error (cyclic redundancy check) and i/o device error.

Is there a way of formatting this drive?

Thanks,
Robbie

I am running into this issue on a Xenserver 6.5 Installation.  I'm looking for an expert who can help recover the disks or guide one of our IT guys on a way to investigate it more thoroughly.

Our Xenserver installation is running into the following error:


The problem is when the virtual machine boots it shows this error in console:

« Processor 1: Xen® Virtual CPU

XS Virtual IDE Controller Hard Drive (0MB)
XS Virtual ATAPI-4 CD-Rom/DVD-Rom

iPXE (http://ipxe.org) 00:04.0 C900 PCI2.10 PMM+00100010+00111020 C900

Press F12 for boot menu.

Boot devide: Hard Disk - failure: could not read boot disk

No bootable device.
Powering off in 30 seconds »

Additionally XenCenter storage tab reports the size correctly but shows occupied space is much larger than it should be.  We moved all the remaining working VMS off the machine, and it's still showing the same occupied space size.  Path also does not show up correctly.


I need someone who can diagnose and correct the issue of VDI not available, VDI failed to load immediately.  Someone who we had working on this says that the "identity has been lost"

This is really far beyond my expertise and am hoping that there is some sort of way of saving these VM'sShows that 99% of the drive is used. Other image will show that the VMS are no where near that size including the snapshots.image-2-.png

Hi

We have a laptop and due to GDPR, i have to encrtpt the laptop with Veracyrpt.
The staff had kept very valuable data on the Hard disk  desktop and didn't back it  up...

The laptop was not booting poperly and i removed the hardisk and and connected to the hardisk caddy to see if i can recover the data and unfortunately it detects the disk if i open , it says i need to format the disk before i use it.

If i clcik cancel it says F:| is not acessible, the volume dosent contain a recogonised file system.Please make sure that all the required file system are loaded and that the volume is not corrupted.
I tried mounting the hard disk through Vera crypt software and also using the rescue disk still it doesn't work.

Please help , the staff will be the most happiest if the data is recovered.
Any help will instructions will be great.

Thanks

I have a clients 2TB Hard Disk Drive that is failing.  My W10 PC can still read the Recovery partition OK but slow.  There is one file on there that I was able ot copy over to my drive.  However the main operating partition is showing up as a Drive on my PC but there is no partition showing.

I have tried to get GetDataBack for NTFS to read the drive but it comes up reporting significant unreadable sectors and then cannot read any data on the main partition.

I am wondering if there is any other software people recommend to attempt data recovery from a failing hard drive.  

I would like to do everything I can before I need to recommend to client to take the drive to a Clean Room at significant cost.

Just for full disclosure, I've already posted this question on the Western Digital community forums, but I've come to value the level of contributions and input from the Experts' Exchange, so I wanted to share my experience here to see what else I might hear from any of you.

Recently, I discovered a disheartening problem with a piece of my equipment, and the prospects for straightening it out aren't great, based on my own research. Long story short, I have a WD Passport portable hard drive that has been working pretty decently for the better part of the last ten years since buying it at my college's bookstore. Unfortunately, I had a mishap while my device was in transit: carrying it in a box up a staircase, it started to slip out as I got up the stairwell; I managed to make it to the top in time, but the hard drive fell out just as I got past the threshold of the door. My intent was to hurry inside to carefully set the box down, or at the very least have the fall be cushioned by the carpeted floor rather than have it tumbling down the hardwood staircase. It seemed pretty harmless at the time, so I didn't check it immediately that night. but over this past weekend, I needed to hook it up to my computer, and I found that it wasn't working anymore. I immediately did some online digging and found that this is pretty common; not only that, I've seen WD

Trying to restore data from a NAS drive. So i have this Bufalo NAS Terrastation, and the fan died, so i am trying to recover the data from, usually, i just use something like knoppix, but when i boot Knoppix up with drives attached, it doesnt see the drives, it must be something to do with the Raid thats installed, i can see the drives in the BIOS no problem and they have passed all tests ( i was worried with the fan not working they may have overheated)

Setting up the back up server for Azure backup on Prem, I get the notification "You are not connected to the internet" . Has anyone encountered this errors when registering an op prem server for Azure backup and recovery.

Hi,

We use Seagate STDR5000200 external hard drives for backing up our data on our systems each month.

These systems we backup data for would include Windows 10 Pro, Windows 7 and Windows Server 2003, all systems are using BIOS.

The Seagate STDR5000200 external hard drive we have contains every piece of data for our business such as databases and Microsoft office files.

We prefer to keep our external backup drive portable so that we can bring our external drives offsite.

This drive is replaced each month at a time by another drive which contains backup data where we switch between two drives each month backing up our systems.

These external hard drives are formatted as NTFS.

These drives are recognised by all our PCs.

We have had a problem with these Seagate external hard drives where, if we have a backup running and the power of our PC goes off, the drive becomes corrupt and we lose our data.

This has happened with our Seagate drives more than once.

What would be the best external hard drive to use for backup of our system's data that is fail safe and portable?

Thanks,
Robbie

i want a solution to back up my Microsoft exchange 2016 database and enable me recover mailboxes. i have gotten to end of life on Evault and we are retiring the services due to cost implications. any recommendations?

Note that i have a DAG set up on premise and i intend to do a direct back up to Azure, But that does not solve the problem of recovering mailboxes or old  emails.

Thanks!!

Testing some backup images we have for older servers after a disaster recovery scare. I have a System Image backup from a Windows 2008 R2 exchange server that gets generated by our backup system (Ahsay) using windows server backup

I am trying to test the restore file doing a bare metal restore on a virtual machine on hyper-v 2016

I run through the 2008r2 install media, repair your computer, re-image, load the image from the network, and am immediately hit with the following error:

----------------------------------------------------
The system image restore has failed.

Error details: The device is not connected. (0x8007048F)
----------------------------------------------------

I can't seem to find any details about anything like this on the internet. I am wondering if this backup is bad? Theres literally nearly nothing for this specific error in this specific instance anywhere that I see. It doesnt help that the error itself is incredibly vague.

There is only one virtual hard disk attached to this machine, and it is larger than the source computer's hard disk.

This is my first deep dive into using Windows System Images so it's quite possible I just don't understand how to do this correctly, but from what research I've done on line, what I am attempting to do should not only be possible but completely straightforward.

There's a request for "Change runbook" that documents/records changes from Day 1
so that in the event of bad changes (malicious or inadvertent ones) being introduced
over along the line of changes, we can rebuild a server/system back selectively,
dropping the "bad" change so that we can bring up the system to a "clean" slate.

Was told it's not "Change Control" nor CRs that we are looking at here.

I've suggested that a 'bare metal' backup be done with incremental backups (think
EMC has one such product) but this is not what the team requires.

Any document, tools or method are much appreciated.

I have a Windows hard-drive from my previous computer that got corrupted in a very weird manner.
All the files in the hard-drive had their size capped to 64 KB (I connected the hard-drive to my existing computer via an external adapter).
No files seem to be missing from this hard-drive, but file sizes range from 0 to 64 KB, but never more than that.
If a file was originally less than 64 KB, e.g. a small text file - I can view it normally and all is great.
If an image file was, say 2 MB, I see it as 64 KB, and when opening it in a photo viewer - it shows the image's first couple of rows of pixels, and then the rest of the image is corrupted.
Other file formats, e.g. a large DOCX file that now appears as 64 KB large cannot even be opened.

I don't know enough about Windows filesystem and how file-size is computed / stored in the file system,
but it seems like the table that stores the file-sizes somehow got corrupted, or maybe some other attribute of the hard-drive got corrupted, like the allocation unit size ? (shooting in the dark here).

It just seems like all the data is still in tact in the drive, but not reachable because the file sizes got messed up for anything over 64 KB.

Any help would be extremely appreciated !

Lambda backups via AWS - Currently the backup script in place does the backup perfectly fine however it does not add the label to the snapshot. We would like the backup to place the instance name to the snapshot backup so it is easy to understand. I believe such functionality must exist already as having a snapshot created with no label is not helpful, especially if that instance no longer exists.

Current Script:
import boto3
import collections
import datetime

ec = boto3.client('ec2')

def lambda_handler(event, context):
    reservations = ec.describe_instances(
        Filters=[
            {'Name': 'tag-key', 'Values': ['backup', 'Backup']},
        ]
    ).get(
        'Reservations', []
    )

    instances = [
        i for r in reservations
        for i in r['Instances']
    ]

    print "Found %d instances that need backing up" % len(instances)

    to_tag = collections.defaultdict(list)

    for instance in instances:
        try:
            retention_days = [
                int(t.get('Value')) for t in instance['Tags']
                if t['Key'] == 'Retention'][0]
        except IndexError:
            retention_days = 7

        for dev in instance['BlockDeviceMappings']:
            if dev.get('Ebs', None) is None:
                continue
            vol_id = dev['Ebs']['VolumeId']
            print "Found EBS volume %s on instance %s" % (
                vol_id, instance['InstanceId'])

            snap = ec.create_snapshot(

Thanks in advance for your help.

I have an external 3 TB OWC Mercury Elite – AL Pro Hard drive.  That is no longer working properly.  I am trying to recover my data.  Windows file Explorer shows the drive but when I click on it, it looks like it is going to load the contents but is no longer able to.  I then get an error message that reads “G:\  is not accessible.  The parameter is incorrect.”  It has also asked me if I would like to format the hard drive which I always say “no.”  

I ran from the command prompt - chkdsk g: /f /r and it was not able to fix the issue.

I have now tried to use Stellar Phoenix Disk Recovery and the software recognizes the drive.  It shows that the drive has data stored but I cannot see the contents.  I initiate the scan it requires and everything seems to be working normal.  Then after 15 or 20 minutes.  Windows file explorer intervenes and I get a message that says, “USB device not recognized.  The last USB device you connected to this computer malfunctioned, and Windows does not recognized it.”  The scan then messes up and I hear the chime that the drive would make when you are plugging it or unplugging it from the computer.  This chime and message will keep reappearing about every minute or so afterwards.

I have tried connecting hard drive to another computer and all the same things happen.

Things to know:

I am using windows 10 pro on my desktop computer (which is where I always kept external hard drive connected) and windows …
