To download a backup file from the Plesk's storage:
In order to improve backup security, we recommend that you protect the backup with a password. This makes it impossible for an attacker to obtain sensitive data in a situation when the security of your backup storage is compromised.
Note: If you forget your password, it cannot be recovered. Therefore, it is strongly recommended to keep a list of your passwords and corresponding backup file names in a safe place.
When somebody downloads a backup from the server, Plesk creates a temporary archive file with the backup on the server. By default, this file is located in the
/tmp directory. If there is not enough disk space for storing the temporary file on the corresponding partition, downloading the backup file will be impossible. To avoid such situations, you can change the location of temporary backup files on the Plesk server by editing the
DUMP_TMP_D variable in the
/etc/psa/psa.conf configuration file.
