Issue Cannot restore Acronis Backup (Cannot access the backup)

[Daan Verbaan]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

Plesk Obsidian 18.0.72 Update #3 Web Host Edition

Hi, I have Plesk server (Obsidian) with the Acronis Plugin installed. Backup procedure runs fine and backups are visible in the Acronis Dashboard as well. However restoring a backup from the Plesk Interface isn't working. Not even close, I'm not able to load te back up and get the details. After a very long time with a spinner 'Loading the backup. This may take a while.

' , I get the error: 'Cannot access the backup created at September 23, 2025 at 12:48 AM.', that's it.

Can anyone help me out how to solve this problem?

Thanks, Daan

Check:
/usr/local/psa/var/modules/acronis-backup/srv/log/main.log
/var/log/plesk/panel.log
for errors related to it

If you see errors like:
{"status": "failed", "fail_reason": "timeout_exceeded"}
or
Unable to mount recovery point

You might need to increase the default timeout for Acronis:
/usr/local/psa/var/modules/acronis-backup/srv/config.ini

[app]...mounting_timeout = 3600...

Default is/was 60 so try 3600, and the same in
/usr/lib/Acronis/system_libs/config

export ACRONIS_MOUNT_DAEMON_TIMEOUT=3600

Then restart the services and retry

service acronis_mms restart
service acronis_plugin restart
