You cannot create a RAID array between the two units but since they are the same model you should be able to back one up to the other.
What you want to do is setup a backup job like you had it doing before, but istead of doing a "Normal" backup would want to use one of the other four Modes. Here they are:
Backup Mode:
Normal Backup:Saves as "yyyymmddhhmm\sourcename\data". Makes a new folder for each backup.
Overwrite Backup (Complete/Append)<labeled incorrectly as the first "Overwrite Backup (Complete/Differential)" on Linkstation Pro, Linkstation Live, Terastation Pro II, and Terastation Live>:
Saves as "_backups\sourcename\data". Does a complete backup every time, if a file is on the destination that is not on the source, it will not be deleted.
Overwrite Backup (Complete/Differential):
Saves as "_backups\sourcename\data". Does a complete backup every time, if a file is on the destination that is not on the source, it will be deleted.
Overwrite Backup (Append):
Saves as "_backups\sourcename\data". Does a complete backup the first time, subsequent backups only send the changes. If a file is on the destination that is not on the source, it will not be deleted.
Overwrite Backup (Differential):
Saves as "_backups\sourcename\data". Does a complete backup the first time, subsequent backups only send the changes. If a file is on the destination that is not on the source, it will be deleted.
Pretty much Complete backups do a complete back up everytime (overwriting files). Append backups will not delete a file that has already been backup, if that file was deleted from the source (other LS), Differential backups will delete that file during the backup.
