When attempting to back up Plesk to an external FTP repository, the process fails with the following error:
Error: The backup process failed: Not enough free disk space to backup selected objects. At least #### Mbytes free disk space is required.
The dump have been made successfully but can not be imported to FTP due to errors.
The dump 'backup_info_1310131347.xml' has been left at repository. Please export it manually
The backup session logs show the following error:

This is considered to be correct behavior. Feature request PPP-111 (Streaming upload to FTP) has been created and it was fixed in
Plesk Onyx .
There is insufficient free space or free inodes on the partition where the
/usr/local/psa/PMM/tmp/ directory is located. Before uploading backup files to a remote FTP repository, Plesk creates an archived copy of the backup files in
Plesk 12.5 ). It then uploads them from this directory to the remote FTP-server.
- Perform the upgrade to
- Free up some space on the partition where the
/usr/local/psa/PMM/tmp/directory is located:
# df -h /usr/local/psa/PMM/tmp/
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg00-usr 4.0G 1.5G 1.1G 39% /usr
# df -ih
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/mapper/vg00-usr 1.3M 1.3M 0 100% /usr
For example, if a full server backup takes 10GB (as listed in Plesk Backup Manager), then there should be at least 10GB free on the partition where
Plesk 12.5 ) is located.
Note: it is may be enough free space, but it is possible that not enough free inodes.
