Question

Hi All,

During a restore from a single file from an VMware Image Backup with more than 7GB the restore fails after 60 minutes with the errormessage above:

After a little research i found the following Information in the Avamar VMware Guide 6.x

When restoring very large files, single-file copy operations that take longer than 60 minutes will fail, causing that entire restore operation to be terminated.

The file we try to restore is only 30GB and we have 7GB of restored data within 60 minutes. Does anybody has experience with such an issue?

The problem is reproducable with files larger then 7GB.

Any help would be greatly appreciated.

Thanks and regards,

Andreas

This issue has been fixed in Avamar Version 6.1.x and the timeout values have been increased.

Sameer_Khan · Answer

There is a hidden flag available to increase timeout. I would recommend contacting support for the same.

schallean · Answer

Thanks for that information. Case has already been opened.

But my Question is. Why does it take nearly 60 Minutes for 30GB File and after 60 Minutes were only ~7GB restored???

This is also interessting.

Thanks for support.

Andreas

Same issues here. Did you already solved this? And how? Best regards

jpsmeele · Answer

Something to do with esg127567? We noticed that each time upu try to restore a big file, each time the size of the file which is restored is different.  Best regards

Sameer_Khan · Answer

If there is a need to restore large sized individual files, guest level backup is the best option to go for.

jpsmeele · Answer

Yes, there is a need. It's not handy to make a guest level backup and an image level backup. Incidently we need to restore a large file, because a image level backup is stored at least a Year, it's very handy to restore a file from the image level backup instead of a second (and same) guest level backup. Best regards

Maybe as workaround. Restore image as a new VM-server, add disk to an existing VM and copy file to the correct place. It looks to work for us. Good luck

schallean · Answer

The workaround sounds good, but if we need to restore a file for example with ~30GB and we have a VMDK Image file with 500GB, it´s hard to restore the whole VMDK file just to get the needed 30GB file. There is also the need for the necessary disk space, which could cause issues for a few customers.

schallean - can you give more info on that. I am on 6.1.x and I cannot restore anything large froma vm backup.

I have to restore to a restore vm and cross mount the drive on the original server so we can copy/paste.
