Backup Duration

During a full initial backup, a backup of 800GB may take up to 10 hours. Daily backups, may take up to 3 hours each. Weekly and monthly backups may take longer. These numbers may vary.

After the initial backup, the backup process transfers only files that have changed since the last backup. Thus, subsequent backups should take less time than the initial backup. The time required for subsequent backups depends on the amount of data accumulated, how many files have changed, and to what extent the files have changed since the last backup.
