Instructions on how to troubleshoot and resolve issues with disk/partition backup failures Introduction
Backup of drives or partitions may fail due to a variety of reasons, but not all reasons are specific to this type of backup. Generally the problem can be treated as a partition backup failure only when you also tried to run a file backup
of the same source (e.g. backup of the whole C: partition)
to the same destination (e.g. to a network share)
with the same backup settings (VSS settings, etc.)
and in the result the file level backup worked. In this case proceed as described in the solution section.
Otherwise it's a general backup failure. In this case please check articles listed in the
More information section. Solution
Follow step-by-step instructions below to troubleshoot the issue.
File system should be supported
All necessary components should be installed
That is relevant for a Linux machine. If snapAPI module was not installed you won’t be able to make partition backups but file backups will work without snapshot using the Operating System API.
On a Linux operating system issue command
dkms status .
Correct output should be similar to
snapapi26, 0.7.69, 2.6.32-279.el6.x86_64, x86_64: installed
If you see another output, repair Agent for Linux installation.
User should have sufficient rights for backup
Drive should be error-free
Sufficient free space in the backup destination
Make sure the backup destination has sufficient free space for a disk backup (a smaller file backup might succeed in this case).
If the steps above have been executed and the issue still persists, collect following information and
contact Acronis Support.
Description of the issue
Please provide a step-by-step description of the issue:
what was chosen for the backup;
what was the backup destination;
which backup settings were applied etc.
Acronis Backup 11.7: Export the failing backup plan: right-click on the plan ->
Full log of the backup
Save the full log of the failing backup plan: in Acronis Backup 11.7 right-click on the plan ->
Logs -> switch to Events -> Save to file.
Collect System Report from the machine in question:
There are several reasons for both disk-level and file-level backup failures. Here are solutions for these issues.
A backup fails because of an application crash
A backup fails because of an authentication failure
A backup fails because of a snapshot issue
