Backup fails with error on snapshot

Post by Hermann »

Case #03438341

Hi,

I'm successfully running veeam-for-linux since 2017 on my personal notebook – actually veeam 2.0.1.665 under Linux Mint 17.3.

Last good backup is from 2019.02.09. From then on all attempts to backup failed with I/o-error on snapshot. As far as I understand snapshot is only written on a partition of running system but never on a external (usb)-media.

/dev/sda5 /boot ext2 220MB free 177MB
/dev/sda6 / ext4 23GB free 16GB
/dev/sda7 /home ext4 66GB free 19GB

A check with fsck of partitions /boot, / and /home found some inconsistences and bad blocks on /boot and / which have been repaired. /home was perfect – no errors at all.

But this did not help with my veeam job concern.

What I tried more is:
- to delete large files from /home partition to be sure to have enough free space for snapshot,
- to put snapshot once to / and next to /home partition via veeam.ini (type=common)

Even that without success.
Strange that the job ends always at the same offset of shnapshot file [/dev/veeamimage1]
“Failed to read from device file at offset [183500800]”. “processed blocks: [377]”
– no matter where snapshot is located - on / or on /home:

Full last successful job logs and first failed job logs as well as veeamsvc.log here:

Here some lines from job.log,

Any helpful advice is very much appreciated.

Hi,

As I can see the support engineer has requested a full log bundle from you. Would you kindly update the logs by the link with the full bundle too?

Thanks!
