Backup error - POSIX: Failed to write data to the file

[siaalien]

Hi all!

I have a CentOS 7 VPS server which I was backing up using VAL 5.0.2.4567 on a SMB share (hosted on a Synology NAS).

It worked well for a few months and then suddenly it started to fail. The messages veeam agent is displaying are:

Code: Select all

08:50:02         Job VPS-1 started at 2023-04-29 05:50:02 UTC

09:57:37         [error] Processing finished with errors at 2023-04-29 06:57:37 UTC

It fails both on full backups and incremental ones.

Here is what I tried:

• - deleted and recreated shared folder on NAS
  - deleted and recreated user on NAS
  - deleted and recreated backup job in VAL
  - completely removed VAL 5.0.2.4567 and installed VAL 6.0.0.1160

My server is CentOS Linux release 7.9.2009 (Core)
Kernel: 3.10.0-1160.81.1.el7.x86_64

Did any of you had a similar problem? Any help is much appreciated.

Thank you!

All the best!

Hello!

My Support Care number is 06038346. I am not sure I will get any support, as my trial for Veeam Backup & Replication Trial expired a few weeks ago...

Thank you!

All the best!
