- Plesk Onyx for Linux
Note: This article has the reference to the issue with the fix available:
Scheduled FTP backups are not rotated. In the backup log file like
/usr/local/psa/PMM/logs/backup-2017-03-29-07-31-10-590/backup.log, the following message appears:
Error 31 FTP: command REST failed
Curl error: (31) FTP: command REST failed: Last FTP request: REST 195307: Last FTP response: 501 Resuming transfers not allowed
This is Plesk bug with ID #PPPM-5902 which was fixed in Plesk Onyx 17.0.17 Update 24 .
Install the latest Plesk micro-updates.
As a workaround, enable REST command at the FTP server.
