Backup formats

An archive backup copies the database file and the transaction log into one or more files, typically on a tape drive. You can only perform archive backups as server-side backups.

You should use an archive backup if you are backing up directly to tape. Otherwise, an image backup should be used because image backups are easier to restore.

An image backup makes a copy of the database files and/or the transaction log, each as separate files.
