After starting the Plesk backup procedure, a backup file is created, but the backup task fails with the similar error in the 'migration.result' file of the corresponding backup session:

<?xml version="1.0" encoding="UTF-8"?>

The issue may be caused by an incorrectly formed /etc/psa/psa.conf file. Open it and check the value of the DUMP_TMP_D variable:

If it is "/var/tmp " instead of "/var/tmp" (note the extra spaces at the end), then the backup tasks will fail on this server.


Remove the extra characters from the DUMP_TMP_D variable in the/etc/psa/psa.conf file.

It is recommended that you re-run the backup task after modifying the file to make sure that the backup is valid.
