Don't have much documentation at my new place and I wanted to know where to begin to understand our DR/BDR information.  I specifically wanted to know what it costs the company to be down for an hour or a day and so forth.  Since we don't have much documentation, it is really hard to understand or where to begin.

I have a LG Gram with 1TB of SSD.  It is partitioned into drives C, D, E, F, and G.  It stated acting really funking following some sort of uSoft C++ update yesterday.  It would lock up, or be really slow, or OK performance but the cursor would constantly blink with a action "circle."  So I reimaged from a Acronis True Image image of two weeks ago.  TI says it has successfully been restored, but it will not boot.  I figured out the BIOS entry, but regardless of boot order it falls down to "Start PXE over IPv6".  I have been struggling for two days, so decided to give up and just do a factory reset, but cannot find how to trigger that.  Meanwhile, I came across WIN RE, which might fix my boot issue, but I cannot find any instructions on how to get into WIN RE except by first selecting it then restarting from Windows 10.

I would like to give WIN RE a go before I go the nuclear route.
Attempting to restore 200r2 server from Windows Backup on a 2TB Seagate Portable HDD and recovery isn't recognizing the drive.  Not only that but the server is either not booting or booting extremely slow when the drive is even plugged into the server.  I can plug the drive into a Win10 machine and it's recognized (and can see the data on it) normally.
Which is the Best Data Recovery Software?
What are the best practices in light of ransomware attacks. I've had a few local non rotating backups get bricked because of ransomware. I do have remote backup, but is everyone resorting to rotating backup drives?
Dear all,

I'm really stuck for a backup solution for a client of mine. What I am trying to achieve without spending any more money is as follows:

Back up an Archive folder that is on the Synology and a full weekly backup of the server (stored in a share called Weekly Backup on the Synology) to a USB drive plugged in to the Synology which is then removed every Monday and swapped for the other USB Drive.

The set up is as follows:

1 x Dell Poweredge Tower Server running 1 x VM Server 2016 as a domain controller

1 x StorageCraft ShadowProtect SPX software installed on the VM, backing up to:

1 x Synology DS216 NAS Drive which has 1 of two 4TB USB Hard Drives plugged in to it on a weekly rotation.

The way I have it set up at the moment is for ShadowProtect to backup the server to the Synology daily but carry out a weekly backup each Friday night and store it in a different folder on the Synology.  I then use HyperBackup on the Synology to back up the Archive Share and the Weekly Backup Folder to the USB Drive every Saturday (I have 2 backups set up, one to each USB drive, 1 backup will always fail each week as the wrong hard drive is plugged in but that's the only way you can do it)

The issue I have is that the Weekly Backup folder contains backups that always have unique names, even though it only ever contains 1 weekly backup the differing names mean that they keep accumulating on the USB backup filling it up.

I only ever need 1 weekly backup stored …
Have an AD server at the main office and a failover server in a branch site
In addition, I have other servers and PC's in the main office which is being replicated to the branch office.

My question: I have in the branch office a PC which I want to replicate to the main office, can a server act as a primary server and replica?

All server/PC are hyper-v, Server 2012, in the same domain.

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'])

            snap = ec.create_snapshot(

Our Datacenter Ops Team reported the following error regarding a NetBackup failure on one of our Hyper-V virtual machines that's a member of a cluster:

I want to ask below question in forum related to data recovery of 750 GB file inside a lost 2TB internal disk:

Problem description:

Currently I am using easeus data recovery professional to try to recover in  XP machine.
While recovery is working fine for small files, it seems to take forever to recover this 750 GB file to internal or USB target disk.
What happens is that after reaching to say 450 GB it comes almost to a standstill with very limited progress for days.
Since both scan and initial recovery are working  fine in XP, I doubt that moving disk to WIN7 would make much difference.
Have tried other tools also, like stellar data recovery and systools hard disk drive recovery, but these tools don’t seem to work in XP (although they claim so).

Hence my question is if anybody has recommendation for best professional tool to recover giga size files.


I am looking fr advice on a backup strategy. Currently my environment has the following specifications:

2 x  VMWare ESXI Hypervisors connected to a SAN with 12 Virtual machines
9 TB of storage space
Physical server (end of life) that has an LTO 5 tape backup unit capable of 10+ TB of storage; It is connected to a cheap 54 TB NAS which holds all backup data
Licensed with Veeam Enterprise 9.5 (to backup VM's)
Licensed with Symantec Backup Exec (archive data to tape)

The above description for backups (and more or less disaster recovery) is in my opinion an outdated method of doing backups. I would like to move to a more modern method that meets the company goals.

I would like to do the following:

Have a retention period: 30 Days, with ongoing monthly backups
-preferably ability file level restore
-Backup to cloud or offsite data center
-Ability to restore images in Amazon (or another ESXi server) in the event of a disaster at HQ
-RPO of 24 hours
-RTO of 4 hours (if possible)

Data is safe and destination of backups needs to be a proven reliable source. Backed up data is encrypted.

I am on a tight budget.

One of the recommendations on this site was to use CloudBerry with Backblaze. I am not certain if this a good commercial solution for Disaster Recovery and backups

I still have the ability to backup everything to disk and then archive to a cloud storage vendor, although I imagine restoring data would be quite slow, even with a Gigabit …
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 …
I have a Hyper V server  with 3 guests.
The host only has one partition so hyper v is running on the local C: drive.

I'm going to do a one time backup just for disaster recovery purposes. In case the whole server goes.
Would it be beneficial to do a one time backup of the whole host using windows backup?
And then I could restore the virtual machines using image restore to the VM.

This customer uses Datto Backup for the guest servers.
I am looking to use a  MY Cloud Pro 4100 series NAS box  for backing up  Windows Server\ SQL Data locally and then send it to Amazon S3 cloud. The servers I am talking about are 3 Windows servers

2 of the 3 servers are VM-* the servers do  have SQL databases

I  would like to backup  the data locally on the NAS and then send it to Amazon
Has anyone done this?

What I originally wanted to do was install the backup software on the NAS and  have the data back to it and then to the Amazon s3 cloud

Exchange 2016 DAG:

Originally I planned a 3 node DAG. But 2 of them are at sites that are regionally near each other and power or internet isn't common, but still not completely uncommon. It has only effected one of the sites 90% of the time, I'm but worried about that last 10%.
If something did effect both of them I'm left with 1 vote out of 3, and if I understand Microsoft's documentation correctly in an odd numbered DAG the FSW is ignored, and the vote would still be split event if it did use it.

So my revised idea is 4 node:
(Site B and C are my concern above)
Site A - 2 Nodes
Site B - 1 Node
Site C - 1 Node

Site D FSW
Site E Alternation FSW
(Site D and E are completely outside the region for all nodes, but it's not realistic to place a Node there)

So I already know this will work, my question in, lets say Sites B/C are down.
I'm left with 2 out of 4 nodes plus my FSW. Now lets say some idiot restarts my FSW or it just goes down.
Does my Alternate FSW take over with no downtime under these conditions? Or is there a period of being dismounted?

I understand that with all nodes up my FSW makes no difference in uptime, I'm just speaking about losing my primary FSW with 2 out of 4 nodes down and my Alternate FSW available.


And actually second question, lets say I only had a primary FSW, 2 out of 4 nodes are down, FSW goes down the database goes down that I know. My question is when that FSW come back up can I remount the …

Andy's VMware vSphere tip#23: Missed my vSphere Tips! Today lets discuss BACKUPS!

After visiting many clients, a high percentage, run BACKUPS, and have backups, but NEVER test a restore!

There is no point in making backups, if you never test restore weekly or monthly to check you can restore a VM, files or folders, and the procedure to do it. In the heat of the moment, when you are facing an emergency, do you really want to be left reading the manuals, on how to restore a VM, or files and folders.

So take some time out, and practice restoring VMs, files and folders using your backup software!


Think about it...

Have a Good Weekend.

If you would like to discuss this post further please post a question to the VMware Topic area.
Someone showed me the Shadow Explorer app (https://www.shadowexplorer.com/) and claimed that the Shadow Explorer program allows you to obtain past versions of all files within your Windows 10 OS that are located in any location on your hard drive (not just in the locations that are shared).

Is this true? Do shadow copies actually backup the contents of the entire hard drive's files? I can see how this can be possible since an initial backup would be done and then subsequent backups would simply backup new file as well as any changes that were made to existing files. However, on the other hand, it seems like this would be limited due to the Disk Space Usage "Max usage" section of the System Properties' Protection tab (see the screenshot).

So is it true that shadow copies actually backup the contents of the entire hard drive's files and that by using a program like Shadow Explorer past backups of files can be recovered (based upon the days and times that past shadow copies were performed)?

As a videographer, what is the best practice for backups? I deal with large files (High-resolution megapixel stills and 1080p/4K/8K video footage) on a daily basis and want to make sure there’s a backup at all times.

Presently, our team uses External Drives but this is difficult to manage and if one of us is out of office, we don't have access to the other's data or backup.

Can someone provide a better scenario for backing up very large datasets which would include a disaster recovery/archive option, secure online retrieval if another staff is out of the office? Our office uses mostly Macs.

Thank you.
Dear Experts, in case of disaster, such as viruses, ransomware,... if we only have NAS device remaining and it only includes the Veeam backup files (.vbm, vbk, .vib files) of Exchange server; can we recover it?

If we cannot recover the VM, how can we rebuild it from those backup files. Can you please suggest a plan? Many thanks.
