Failed to backup file

Veeam Logoby UT2015 » Thu Feb 04, 2016 1:55 pm

Hi all,

we have the problem that sometimes an endpoint backup finishes with warnings. The warning itself says "Failed to backup [filename]".

The logfile of the Job states the same:

Code: Select all
[03.02.2016 21:58:52] <44> Info           [AP] (ac25) output: --asyncNtf:--wn:Failed to backup [filename]
[03.02.2016 21:58:52] <29> Info           [AP] (4968) output: --asyncNtf:--wn:Failed to backup [filename]
[03.02.2016 21:58:52] <45> Info           [AP] (e513) output: --asyncNtf:--wn:Failed to backup [filename]
[03.02.2016 21:58:52] <44> Info                   [AP] (ac25) warning: Failed to backup [filename]
[03.02.2016 21:58:52] <29> Info                   [AP] (4968) warning: Failed to backup [filename]
[03.02.2016 21:58:52] <45> Info                   [AP] (e513) warning: Failed to backup [filename]
[03.02.2016 21:58:52] <29> Warning  Failed to backup [filename]


What does this mean? The file was probably not accessed by any other application at that time, so what is the actual problem?

Regards,

Hi,

May I ask some questions?

1. What kind of file is that?
2. Where does the file reside at?
3. How big is it?

Thank you.

Hi,

1. It is a file belonging to a backup of a different VM environment, which cannot be directly backed up by our B+R (essentials). The procedure is:
- a) VM environment backs up to share on Server A with VMware data recovery
- b) some other physical servers back up to Veeam repository on Server A with endpoint backup
- c) Server A actually backs up itself (Veeam repository excluded) to the Veeam repository with endpoint backup
- d) Veeam B+R running on Server A backs up Veeam repository to tape
- Step c fails sometimes while reading files of the VMware data recovery (which is not active at that moment).

2. The file is located on a local drive in a not too long path: F:\external_backup\VMwareDataRecovery\BackupStore\000\slab-930

3. The size is approx. 1 GB.

Although your configuration is quite tricky I can't find an explanation why the backup fails. Please open a case with our support team. Aslo may I ask you why your VM can't be backed up with B&R?

Thank you.

We cannot backup the VMs with B&R, because of our license. We have Backup essentials including B&R. We are only allowed to backup VMs running on 6 CPU sockets. We are backing that VMware environment up with B&R. But we have a second (older) VMware environment with another 3 hosts and cannot back that up with the essentials license.

That's why we still need to additionally use VMware Data Recovery appliance.

Is there anything else except B&R and shared folder on Server A? Have you thought about virtualizing it so B&R could backup itself? I think that would simplify the whole schema.

Anyway I still suggest you to open case with support and post your case ID here.

Thank you.

Hi,

the physical Server A does not only contain B&R but also VCenter. The Server A has a lot of diskspace, because we are backing up our virtual environment to disk first and in a second step to tape. So I think it won't make sense to virtualize that Server.

We have made very bad experience with Veeam Support. We did open 2 Support cases so far. We gave a detailed description of our problem to the Support in both cases from the beginning, but the Support Team actually didn't even completely read our description and asked several times for information, which they already got before.

We stopped the first case and found a solution on our own. The second case was not solved by the Support Team, they just played along with us and told us that the (in our opinion severe bug) will sometime be fixed in a future version of B&R (The Backup browser actually has a severe bug: If files/folders from guest operating systems are not restored to the original location, but copied to a different location (via "CopyTo" in backup browser), the names of the files and folders are changed by B&R! Leading dots are removed, which occur e.g. in configuration files of eclipse IDE. A backup solution must never change contents or names of files!)

That's why I don't really want to open a Support case...

May I ask you to provide case IDs for purpose of improving customer experience?

Have you tried to escalate the case ("Talk to manager" button)?

The Backup browser actually has a severe bug: If files/folders from guest operating systems are not restored to the original location, but copied to a different location (via "CopyTo" in backup browser), the names of the files and folders are changed by B&R!

Will pass this to our QA team for deeper investigation.

Thank you!

Hi UT2015,

F:\external_backup\VMwareDataRecovery\BackupStore\000\

One more question: does the VEB account has full access (read/write permissions) to access this folder? Check if this folder is accessible while logged in under the user account with running VEB

I will post them as soon as I get them (from my colleague).

No we did not. We wrote twice in the mails that it is an important function for us, but that did not change anything.

Will pass this to our QA team for deeper investigation.
It is easily reproducable.

I don't unterstand that question. I think VEB is running with the local SYSTEM account which is of course able to access all local files (edit: SYSTEM is contained in ACL of given file and has full Access). The credentials used in VEB are only used to store the backup in the Veeam repository?

The bug is still existing in V9.

UT2015,

Did you manage to get the support case ID by any chance? I'll check with QA team regarding previously submitted bug and follow up shortly.

The case # is 01207808.

We reported that bug 4 months (!) ago.

This is in our opinion a severe bug. It can be reproduced very easy:
- create a file named ".test" in a VM
- backup the VM
- restore guest file
- copy file to a different location than source location
- file will be copied but renamed to "test" (without leading dot)

File names with leading dots are allowed in Windows and they are e.g. used by Eclipse Java IDE.

UT2015,

Thank you for the heads up. I was able to find the case and related bug – discussing it with QA team now.

Hi UT2015,

I was told that there is a solid workaround. Run a File Level Recovery, then minimize the backup browser and navigate to C:\VeeamFLR (the folder used for mounting you backup). Then just drag and drop the needed files from the backup to the desired directory – the file name should remain untouched.
