The Netgear ReadyNAS network attached storage (NAS) unit is designed to provide storage for files and backup data from a home or office computer. The files might be too large or too numerous to store on the computer, or archival files that are infrequently needed. If the ReadyNAS fails, you could lose important files and backup images that would be essential if your computer fails. To safeguard the data stored on the ReadyNAS, you should consider backing up that data as well. One solution is to install a second ReadyNAS and synchronise the files between the two units, providing full access to files and backup images should either unit fail.
Open the Frontview browser application installed when you configured your ReadyNAS units. For each ReadyNAS, click "Services," then "Standard File Protocols," and ensure that the check boxes for "NFS" and "Rsync" are checked. This will allow you to use both protocols for your ReadyNAS to ReadyNAS backup.
Click "Shares," then "Add Shares" for your backup ReadyNAS. You should duplicate the names of the shares you will be backing up from your source ReadyNAS. For example, if you have a share called "Music" on your source ReadyNAS, you should input the same name for a share on your backup ReadyNAS.
Click "Shares," then "Share Listing" for both ReadyNAS units. Make sure that the "NFS" and "Rsync" protocols are active on each machine. If the icon is coloured, the protocols are active. If the icon is greyed-out, click on the icon, and select "Read/Write" from the drop-down menu to activate the protocol.
Click "Backup" on your source ReadyNAS. then "Add a New Backup Job." You should set up a separate backup job for each share on the source ReadyNAS. In the "Select Backup Source" section of the screen, select the share from the drop-down menu. In the "Select Backup Destination" section, select "Remote: NFS Server." Input the path to the share location in the format "myserver:/mypath". An example would be "readybackup/music".
Choose your backup schedule. The backup schedule can be left at the default, because you will only be doing an NFS backup the first time. NFS backups are quicker than Rsync backups, and you will want your first full backup to be quick. Subsequent backups, which will be incremental backups that back up only files that have changed on your source ReadyNAS, can be done through Rsync since speed won't be an issue.
Select "First Time" in the "Schedule Full Backup" drop-down menu. This will perform a full backup, using the NFS protocol, as soon as you click the "Apply" button at the bottom of the window.
Create additional full backups of all of the shares on the source ReadyNAS, using the same procedure. When the backups are complete, you have completely backed up your source ReadyNAS to the destination ReadyNAS.
Select "Backup," then "Backup Jobs" for the source ReadyNAS. Disable all of the full NFS backup jobs you created. These are NFS backups and your future backups will be done using the Rsync protocol.
Create new backup jobs for each of your shares, using the same procedure as you did with the NFS backups. In the "Select Backup Destination" portion of the screen, choose "Remote: Rsync Server" and input the path to the share location in the format "myserver::share". An example path would be "readybackup::music".
Choose your regular backup schedule. The two ReadyNAS units will synchronise their files based on this schedule, every four, six, eight, 12 or 24 hours. You can also select whether you want to do a backup every day or on specific days by clicking the check boxes next to the days.
Click apply. The first Rsync backup will begin, though there will probably be little if any data transferred because you have already performed a full backup. Based on your schedule, the source ReadyNAS will automatically and regularly back up all of the shares to the destination ReadyNAS.
