The File Backup and Recovery function is similar to the Share Disk Replication Backup and Recovery, except
instead of backing up the entire contents of a Share Disk, you choose individual files to backup. Also there is
an additional policy mode
Version
which syncs all file changes in a new folder, effectively saving a new time-
stamped version of the file. The Version policy allows restoration of backed up versions of files, selected according
to the time created.
Keep in mind the following points for File Backup and Restore:
For File Backup:
• The destination Share Disk can be located on a remote NAS or on the local one.
• Files for backup must all be on the same Share Disk.
• Setup a NAS portal configuration before using File Backup.
• For backup to a remote NAS, the remote NAS must “allow” the IP address of the Share Disk on the
original NAS. See “Allow IP for backup” on page 278 .
• A temporary Share Disk snapshot is created if snapshot is available.
• A folder on the destination Share Disk named Backup is created for the backed up files.
• Hard link is used for reserving the destination Share Disk space if there are multiple copies.
• Differential and compression transmission is supported.
• File Backups can be scheduled.
• Other File Backup parameters include retry attempts allowed.
