You can select which protocol you want to use for the job. The options that are available
to you depend on how your ReadyNAS system is configured. Backup protocols are
described in the following table.
Table 14. Backup protocols
DescriptionItem
Source or destination is a share on a Windows computer, or a share on another NAS.
Incremental backups with this protocol use time stamps to determine whether files will
be backed up.
Windows/NAS
(Timestamp)
Source is a share on a Windows computer.
Incremental backups with this protocol use the archive bit of files, similar to Windows,
to determine whether they will be backed up.
Windows (Archive Bit)
Source or destination is an FTP site or a path from that site.FTP
Source or destination is on a Linux or UNIX device accessed using NFS.
macOS users can also use this option by setting up an NFS share from the console
terminal.
NFS
Source or destination is accessed using an Rsync server.
Rsync was originally available for Linux and other UNIX-based operating systems, but
is also popular under Windows and Mac for its efficient use of incremental file transfers.
Using Rsync is the preferred backup method when backing up from one ReadyNAS
device to another.
Rsync server
Source or destination is accessed using an Rsync server.
Rsync data transfers to go through a secure, encrypted SSH tunnel. We recommend
using remote SSH when backups are being transferred over the Internet.

Backups Compared to ReadyDR Backups
ReadyNAS OS provides both file backups, just called backups, and snapshot backups,
called ReadyDR backups. Both operate similarly and both provide copies of your data,
but because of the underlying differences, depending on what you are backing up and
why, one might be better than the other for your specific case.
A file backup is a copy of the file that exists at the time of the back up. The backup
contains no history of the file. (Although you can maintain file history by maintaining
older backups.) A ReadyDR backup consists of all of the snapshots on a share or LUN.
You have the same snapshot history in the ReadyDR backup as you do in the original.
You can retrieve previous versions of a file in the same way you can retrieve previous
versions through the original snapshots.
