• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Unable to create remote backup

mb_martijn

New Pleskian
Server operating system version
CentOS Linux 7.9.2009
Plesk version and microupdate number
Plesk Obsidian Version 18.0.53 Update #1
We have scheduled backup - running daily incremental backup, a full one once a week, keepin 4 full versions. Both server storage and Dropbox.

It will run ok for a day or two, then the remote backup just fails with the following error:
Unable to create the remote backup: Transport error: Extension transport: ext://dropbox-backup/server/: {"error_summary": "incorrect_offset/.", "error": {".tag": "incorrect_offset", "correct_offset": 323026944}}

We have had issues in the past, where you had to reconnect the dropbox or the storage was full, but non of that seems the case at this point. After we looked at it on friday, checked for updates etc., restarted server and it worked on the saturday night backup, but the sunday night backup had the same error again.
 
Please try to check the backup log in /var/log/plesk/PMM/<your backup> if you can find out more about the reason.
