Backing up System Reserved (SYSVOL) partition failed. Image backup failed

First of all, thanks for creating this software. The combination of file and image backups, windows and linux support, incremental and full backups, all making the best possible use of the native OS features is really great and something I haven’t seen anywhere else.

Today I have tried to install UrBackup on my Windows 10 tablet. Unfortunately the image backups don’t work. I have tested client version 2.1.16 and the 2.2.2 beta, with server version 2.1.9.

The backup fails with error message “Backing up System Reserved (SYSVOL) partition failed. Image backup failed”.

Just before this happens, the debug log shows:

I am not really sure what UrBackup is looking for when talking about SYSVOL, but in my case it seems to find some kind of manufacturer recovery partition (“recovery”). “os” is the primary parition (C:) which contains the OS and data files (only partition to be backed up in image mode), data2 is an SD card (backed up in file mode for now), “recovery” and “restore” probably contain recovery data from the manufacturer or Windows.

Can I disable backing up the SYSVOL partition, or can I get UrBackup to ignore the recovery partitions somehow? I could not find a conclusive answer in the forums regarding this (or similar) issues.

Could be it needs to read 4096 bytes at a time. Could you post the output of fsutil fsinfo ntfsinfo C: ?

I don’t know if this is relevant, but I think ?\Volume{6800d510-b9da-4963-a054-d781c54f6382} is some manufacturer recovery partition, not C:

Your specific installation is weird, but newer Windows versions have a separate boot partition (from which e.g. the boot recovery starts) and it tries to backup that one.

See here: https://superuser.com/a/915724/89138

You seem to have that mentioned AF 4Kn disk. Congrats, seems you are one of the first ones :wink:

Good to know I did not miss anything in other forum posts. I did upgrade this one from Windows 8.1 to Windows 10. The missing partition may have something to do with the upgrade, or with the fact that it’s a tablet (Asus Transformer T100TA) with a relatively small SSD drive (and ASUS not wanting to “lose” another GB). The current partition layout is: 100MB EFI, 900MB recovery, 49GB OS/data, 8GB recovery (in that order).

Hello Guys,

did you find any solution for your problem.

I think i have the same problem with my 32 bit windows 10 tablet.

You probably don’t have the same problem.

Hey guys,
i have exactly the same problem, also with an old Windows 10 32 bit tablet.
Sorry for adding to an such old post. But the issue is the same!

Here is the log:

|Info|26.04.23 21:04|Starting unscheduled full image backup of volume "C:"...|
|Fehler|26.04.23 21:04|Backing up System Reserved (SYSVOL) partition failed. Image backup failed|
|Info|26.04.23 21:04|Time taken for backing up client Dintis-Tablet: 1s|
|Fehler|26.04.23 21:04|Backup failed|

I have this partition layout:

Which is the sames mentioned here on Windows 10 legacy/BIOS boot: partitioning - What is this Recovery Partition for on a fresh installation of Windows? - Super User

image

So it seems my partition layout is correct.

Sholdn’t SYSVOL be skipped on those systems?
Any hints how i can exclude the SYSVOL or solve this issue in another way?

thx
