VmProtect backup to NAS fails sometimes

Thread needs solution

Hi,

i have Acronis VmProtect 8 (Build 8184) in a vCenter with 2 physical hosts.

There are two separate plans of backup

In one of the two hosts, backup occasionally fails with this error:

Hi,

This error usually indicates file opening conflict, i.e. when the same backup archive is tried to be opened for write twice. For example if you mount (Run VM from Backup) a VM from the backup, then choose Unmount and Save option to save the changes and at the same time perform backup from separate backup task into the same backup archive. The same thing may happen if there is more than 1 backup task writing data into the same archive file at the same time, so this is the first thing to be checked (may be there are 2 tasks backing up into the same archive occasionally?). Another possibility is that the archive file is locked on the NAS side, i.e. it doesn't release the locks properly and this causes the conflict.

Thank you.
