When trying to back up Plesk to an external FTP repository, the process fails with the following error:
PLESK_ERROR: Error: The backup process failed: Not enough free disk space to backup selected objects. At least #### Mbytes free disk space is required.
PLESK_ERROR: Error: 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 may contain following errors:

This is considered to be correct behavior. Feature request PPP-111 (Streaming upload to FTP) has been created and it is fixed in Plesk Onyx.
There is insufficient free space or free inodes on the partition where the
directory is located. Before uploading backup files to a remote FTP repository, Plesk creates an archived copy of the backup files in
for Plesk 12.5). It then uploads them from this directory to the remote FTP-server.
Perform the upgrade to Plesk Onyx.
Connect to the server via
and free up some space on the partition where the
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
for Plesk 12.5) is located.
Note: it may be enough free space, but it is possible that not enough free inodes.
