- Plesk Onyx for Linux
How do backups to remote storage (FTP or cloud) work?
Starting from Plesk Onyx 17.5, when a backup is configured to be created on a remote storage, Plesk does not create a full local copy of it. Instead, Plesk transfers the backup in parts:
First, a backup file of the largest Plesk domain service (database, mailbox, website web content) is created locally as a temporary archive in
Then this archive is transferred to a remote storage.
Simultaneously with transferring backup to the remote storage, creation of new archive is starting;
After the archive has been uploaded to a remote storage, it is removed from the Plesk server.
Note: Make sure that there is enough free disk space on a Plesk server. Since parts of backup files are created simultaneously, it is good practice to have free space equal at least to the half of full backup size.
Note: Once the backup is completely uploaded to the FTP server, it will contain a tgz file named backup_<YYMMDDHHmm>.tar instead of many files, for example: backup_info_<YYMMDDHHmm>.xml, backup_user-data_<YYMMDDHHmm>.tgz, backup_logs_<YYMMDDHHmm>, etc
