Disaster Recovery

Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.

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

What power outage TRACKING systems do you recommend that would do what my
currently does, but every 1 minutes instead of every 15 minutes ?

My UPS is plugged into a natural gas "always on" generator, therefore the UPS would show a 5 hour
power outage only lasting about 30 seconds, just enough time for it to switch over to natural gas

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.

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?

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.

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(
            {'Name': 'tag-key', 'Values': ['backup', 'Backup']},
        '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:
            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:
            vol_id = dev['Ebs']['VolumeId']
            print "Found EBS volume %s on instance %s" % (
                vol_id, instance['InstanceId'])

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 …

There are numerous software applications for Windows that will help to recover a deleted file on a flash drive formatted as FAT32.  Unfortunately, what I am finding is that these tools are designed to work with standard-sized FAT32 drives up to 32GB.  If you buy a larger SD card - such as a Sandisk 64GB Extreme - what you receive is a drive with a single larger-than-32GB-partition.   Presumably, Sandisk has put a non-standard FAT32 partition on that drive, cheating some element of the specification?

I have a 64GB flash drive with a FAT32 partition, and I need to recover a file.   Wise Data Recovery and Wondershare Recoverit do not see the 64GB flash drive at all.   EaseUS Data Recovery Free application sees the flash drive and claims to work on it for an hour and find 3000 files (which is way too high) and then displays only one folder on the drive and three files.  So EaseUS basically has a corrupted view of the file system.

Is there any software application for Windows that will work with non-standard FAT32 partitions that are larger than 32GB?
I had a couple of VMs configured with vsphere replication and working fine, after upgrading from vcenter 6 to 6.5 I'm not able to reconfigure replication and can't edit RPO policy(greyed out). The workarround to edit RPO policy is deleting the VM , create and reconfigure it again from scratch, what could I be doing wrong? is there any bug in 6.5 related to this?

PD: vmware tools in the vms is out of date due the vcenter upgrade.
I am trying to locate data that is needed by a customer and thought to be in a workstation backup that is stored with multiple workstation backups on a My Passport external drive.

The problem I have is the disk is nothing but .dat files that I do not know the origin of, therefore do not know of a software that will enable me to browse the content.  

I have attached screenshots of the data directory, and was hoping EE could provide some ideas.

I am working on creating an android app that scans the deleted data which is not overwritten by android device and recovers it, just like data recovery tool. How to create a recovery tool inside an android app is there a tutorial or any thing?
we woud like to have Windows DNS Server ( 3 to 4) in main site and 3 to 4 server in DR to provide high availability and Disaster recovery. I need guidance to make a proper design and have following questions.

Can we have three primary DNS servers (two in main and one in DR site) with read/write ability? If yes, then we are plaining to put these server behind DMZ zone and these servers will not be serving client queries.
We will have two secondary servers in main site and two in DR servers (only with read/write option) in DMZ zone to expose them to the internet.
 Is this right approach to design and build DNS Infrastructure to offer DNS services to customer?
