Windows Server 2016 - Automatic Schedule - Invalid location
Hello Everyone,
So this is a weird problem. Using the windows feature backup utility. I am able to back up to a network shared folder only by selecting a manual backup option and it does not ask me for credentials. But if I select the Automatic Schedule backup it will ask
me for credentials and I use the backup operator credentials. It allows me to go to the final step and then it fails with an error "This is an invalid location." I'm like I just did a backup manually, why is it failing when I want to schedule automatic
backups.
Anyone have any ideas or suggestions on what could be causing this?
Later on today I will be scrutinizing logs to see if I can find any errors or warnings that may suggest the reason for the error. I have a couple of places that I will be checking.
Thanks,
PB

Volsnap Event ID: 25 and Loss of Previous Backups
I have a Windows Small Business Server 2008 machine being backed up using the Windows Server Backup utility. The backups are being made to two external USB attached 1TB drives. Each drive is rotated out weekly, meaning that one drive is attached one week, then the other drive is swapped in the following week, ad infinitum for the best part of a year. Two backups were being made each day to the attached drive, one at 12pm and one at 9pm.
About two weeks ago it appears that one of the two drives reached capacity and began shedding the oldest backups, as confirmed by the VOLSNAP Event ID: 33 entries in the System Event log. On the second day, however, ALL shadow copies on the attached backup driver (volume) were deleted, as confirmed by a single VOLSNAP Event ID: 25. (See below for both Event ID message contents.) Unfortuneately, neither events were noted until the drive was swapped out with the other drive and some how the problem was propagated to the second drive, resulting in the deletion of all shadow copies on the second drive, too.
The end result... BOTH drives lost ALL previous backups leaving only the most recent full backup and no clue as to why it happened or how to prevent it from happening again. Virtually no older backup file versions could be recovered.
I was under the impression that, by design, the WSB utility would only start deleting the oldest backups (on a full drive) in order to make room for the newer backups. Granted, had I been keeping attention, I would have actually swapped out the full drives before the actually got full, so that NO data was deleted.
If I'm to continue using the Windows Server Backup utility, I need to know what happened and how to absolutely prevent it from happening again. I never expected to loose BOTH backups at the same time, and due to budget restraints, two rotating backup drives seemed a logical solution.
Here is text from the two VOLSNAP Event ID messages found in the System Log:

NOTE: Though I'm not sure if this has any bearing on the situation, the server is configured to make two snapshots a day of two volumes on the server, however, when I looked at the Shadow Copy settings I couldn't quite be sure if the VSS wasn't somehow also making snapshots on the two external drives, even though I haven't specified VSS to do so. None show up on the two replacement drives I'm now using, so I'd say not.
Information on how to prevent this from happening again would greatly be appreciated. (I'll be making sure no backup drive gets even close to being full from now on, that's for sure!)
Thanks,
Joseph.

Searched around and have seen others with this issue but no real solutions.
I have a 14TB Deduplicated volume that loses its vss about once a month. I just lost this lasts night and have seen some interesting stuff.
First the error

Any ideas here?

Data Loss Event ID 25 "The shadow copies on Volume E: were deleted because shadow copy storage could not grow in time."
It appears that this has been an issue for over 10 years now, and there is yet a resolution to be had.
Once you fill up the available shadow copy storage allocated, then push a lot of disk I/O's, your snapshots will eventually be deleted and you will incur data loss.
Here is how:
When one first creates a VSS snapshot, it shows 50GB of available shadow storage space, which is great:
C:\Users\root>vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2013 Microsoft Corp.
Shadow Copy Storage association
For volume: (E:)\\?\Volume{8a5b0a31-7564-491e-a150-2fc8889ae217}\
Shadow Copy Storage volume: (E:)\\?\Volume{8a5b0a31-7564-491e-a150-2fc8889ae217}\Used Shadow Copy Storage space: 0 bytes (0%)Allocated Shadow Copy Storage space: 50 GB (0%)
Maximum Shadow Copy Storage space: 38.2 TB (100%)But as time goes by, this will fill up and then the VSS service will only try and stay ahead by about 300MB.
So what happens if you push too many I/O's, and the VSS service can't allocate space faster than it is writing? Does it re-allocate the space requested when the disk is idle? No. Does it pause the disk if it needs to allocate more shadow storage? No.
It will simply DELETE ALL of your snapshots.
Eventually, you will fill up the 50GB of shadow copy allocated storage, like so:
C:\Users\root>vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2013 Microsoft Corp.
Shadow Copy Storage association
For volume: (E:)\\?\Volume{8a5b0a31-7564-491e-a150-2fc8889ae217}\
Shadow Copy Storage volume: (E:)\\?\Volume{8a5b0a31-7564-491e-a150-2fc8889ae217}\Used Shadow Copy Storage space: 50 GB (0%)Allocated Shadow Copy Storage space: 50.3 GB (0%)
Maximum Shadow Copy Storage space: 38.2 TB (100%)And from this point on, it will barely stay ahead, except by a measly 300MB, which isn't much when you're dealing with large volumes (the one above is about 40TB).
Here's a snapshot that is just waiting to disappear any day now...
C:\Users\root>vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2013 Microsoft Corp.

Shadow Copy Storage volume: (E:)\\?\Volume{8a5b0a31-7564-491e-a150-2fc8889ae217}\
Used Shadow Copy Storage space: 151 GB (0%) <-- any moment my snapshot could be destroyed!Allocated Shadow Copy Storage space: 151 GB (0%) Maximum Shadow Copy Storage space: 38.2 TB (100%) Note that it stops showing decimals after 100GB, but I timed it as the space increases and the allocated space is still staying around 300MB ahead of the used space.
If you happen to write too many I/O's, you will get this in your event log and ALL of your snapshots will be deleted.
This is not acceptable, and I've seen it on multiple systems from Windows Server 2008 through Windows Server 2016. I need a resolution to this issue because we have customer data at stake, and we cannot move forward unless we know, for a fact, that snapshots will not be magically deleted because the hard drive decided to be slow one day, for some arbitrary reason.
I've also read the Microsoft suggestion of putting the shadow storage on another volume. That is a band aid and NOT a good solution, as that could also incur failures. If for some reason the SAN becomes unavailable, you will lose your snapshots. If for some reason the disk degrades on the second volume, you will lose your snapshots. If for some reason the second volume runs out of space, you will lose your snapshots.
It might also be worth mentioning that the registry setting MinDiffAreaFileSize was also suggested by Microsoft, but that does nothing to alleviate the issue.

Windows Server 2016 Essentials Not Running Scheduled Backup
Hello, I have a Windows Server 2016 Essentials server that I have setup a scheduled backup on. I have it doing a full bare metal backup to an external hard drive. Windows shows the scheduled backup in the Windows Server Backup GUI and in the
Task Scheduler. I can run the backup manually, without any issues, but when the scheduled backup is set to run it doesn't. If I launch the Windows Server Backup GUI it will tell me that the backup is scheduled to run the next day. When I look at
the scheduled task I see that it is using the SYSTEM account and has a Last Run Result 0xC0000142. I have never had an issue with the Windows Backup program and this was a fresh install all I configured on server is to be a domain controller and ran all of
the Windows updates. I haven't messed with any setting or permissions as well. To me if feels like it's a permission problem but I don't understand why, when the backup is running with the SYSTEM account, just like all my other servers. I
have removed the backup schedule and re-added it but that didn't make a difference. I do see where a user was having a similar issue and was being told to add the SYSTEM account to the Administrators Group in Active Directory. I have never needed to do this
and would like to fix the issue and not add the SYSTEM account to this group.

Questions regarding Windows Backup on Windows Server 2016 Std.
Hello,
we have a HyperV Host with 2 Windows 2016 VMs
We use Windows Backup with two USB Drives and switch them weekly.
We have also one Synology NAS.
Do you have a Idea
how we can use the Synology NAS as the primary Target of Windows Backup?
Do you think it is possible to use "daily Windows Backup > to Synology" also with Versionhistory of the last 14 days? (<< it seems thats only possible with USB Drive?)

Painfully slow backups
Experiencing slow backups with the following;
1. Hyper-V host running Server 2016.
2. All 4 VMs have fixed sized virtual hard disks.
3. Virtual hard disks reside on a volume directly attached to the host, currently 176GB free of 4.36TB.
4. Full system state backup and Hyper-V backup being taken with Windows Server Backup.
5. Dedicated 6TB USB 3.0 hard drive used for WSB.
Backup begins at 10pm each evening, Windows Server Backup still running at only 15% 10 hours later.
The USB drive is being written to, at the 10 hour point around 360GB has been written.
Please could someone just run over the mechanics of the VSS process during backup? As I understand it, VSS will create a snapshot of the VM during backup to track changes made during the backup process. Is there any reason why the backup is still only at 15% almost 12 hours later? Hyper-V manager simply reports 'Backing up...'
Many thanks.

Start-WBHyperVRecovery : The specified backup storage location is invalid.
Hi everyone,
I made a backup of a VM on one Hyper-V host. Now I try to restore it on another using Powershell:
$VMName = 'myVM'
$volumeName = 'myVM_bak'
$MachineName = 'host1'
$TargetPath = 'E:\HV'
$WBVolume = Get-WBVolume -AllVolumes | ? {$_.VolumeLabel -eq $volumeName}
$WBBackupTarget = New-WBBackupTarget -Volume $WBVolume
$WBBackupSet = Get-WBBackupSet -BackupTarget $WBBackupTarget -MachineName $MachineName | Select-Object -Last 1
$WBVirtualMachines = ($WBBackupSet.Application | ? Identifier -eq 'HyperV').Component | ? VMName -eq $VMName
Start-WBHyperVRecovery -BackupSet $WBBackupSet -VMInBackup $WBVirtualMachines -Force -UseAlternateLocation -TargetPath $TargetPath -RecreatePath
I get an error "<g class="gr_ gr_19 gr-alert gr_gramm gr_hide gr_inline_cards gr_run_anim Style multiReplace replaceWithoutSep replaceWithoutSep" data-gr-id="19" id="19">Start-WBHyperVRecovery </g><g class="gr_ gr_18 gr-alert gr_gramm gr_inline_cards gr_run_anim Style replaceWithoutSep" data-gr-id="18" id="18"><g class="gr_ gr_19 gr-alert gr_gramm gr_hide gr_inline_cards gr_disable_anim_appear Style multiReplace replaceWithoutSep replaceWithoutSep" data-gr-id="19" id="19">:</g>The</g> specified backup storage location is invalid."
I can restore the VM using Windows Server Backup UI without any problem. But I need to restore the VM every day.
The both Hyper-V servers are Windows Server 2012 R2

Volsnap Event ID: 25 and Loss of Previous Backups
I have a Windows Small Business Server 2008 machine being backed up using the Windows Server Backup utility. The backups are being made to two external USB attached 1TB drives. Each drive is rotated out weekly, meaning that one drive is attached one week, then the other drive is swapped in the following week, ad infinitum for the best part of a year. Two backups were being made each day to the attached drive, one at 12pm and one at 9pm.
About two weeks ago it appears that one of the two drives reached capacity and began shedding the oldest backups, as confirmed by the VOLSNAP Event ID: 33 entries in the System Event log. On the second day, however, ALL shadow copies on the attached backup driver (volume) were deleted, as confirmed by a single VOLSNAP Event ID: 25. (See below for both Event ID message contents.) Unfortuneately, neither events were noted until the drive was swapped out with the other drive and some how the problem was propagated to the second drive, resulting in the deletion of all shadow copies on the second drive, too.
The end result... BOTH drives lost ALL previous backups leaving only the most recent full backup and no clue as to why it happened or how to prevent it from happening again. Virtually no older backup file versions could be recovered.
I was under the impression that, by design, the WSB utility would only start deleting the oldest backups (on a full drive) in order to make room for the newer backups. Granted, had I been keeping attention, I would have actually swapped out the full drives before the actually got full, so that NO data was deleted.
If I'm to continue using the Windows Server Backup utility, I need to know what happened and how to absolutely prevent it from happening again. I never expected to loose BOTH backups at the same time, and due to budget restraints, two rotating backup drives seemed a logical solution.
Here is text from the two VOLSNAP Event ID messages found in the System Log:
Event ID: 25
Source: volsnap
Level: Error
Description: The shadow copies of volume \\?\Volume{93896cfc-d904-11dd-8cb5-001ec9ef572e} were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.
Event ID: 33
Source: volsnap
Level: Information
Description: The oldest shadow copy of volume \\?\Volume{93896cfc-d904-11dd-8cb5-001ec9ef572e} was deleted to keep disk space usage for shadow copies of volume \\?\Volume{93896cfc-d904-11dd-8cb5-001ec9ef572e} below the user defined limit.
NOTE: Though I'm not sure if this has any bearing on the situation, the server is configured to make two snapshots a day of two volumes on the server, however, when I looked at the Shadow Copy settings I couldn't quite be sure if the VSS wasn't somehow also making snapshots on the two external drives, even though I haven't specified VSS to do so. None show up on the two replacement drives I'm now using, so I'd say not.
Information on how to prevent this from happening again would greatly be appreciated. (I'll be making sure no backup drive gets even close to being full from now on, that's for sure!)
Thanks,
Joseph.
