I have a 12TB NAS with ~2 million files on it that I need to backup to an identical device. I previously asked for the best software to make a 1-time copy of the NAS, thinking after the initial copy I could use my normal backup tools. Rich-copy ended up copying all the files over, which is great, but now I need an ongoing backup solution.
Basically what I need to be able to do is:
a) Schedule backups throughout the day, which will sync changes made from the main device, to the backup.
b) When a file is deleted from the main NAS, I need that file to be moved to a folder on the backup NAS (in the past I used SecondCopy's "Backup Deletes" function). Bascially I want deleted files to be removed from the main backup, but copied to another folder, so that I can recover it if the deletion was done by mistake.
In the past I have used SecondCopy for this, but the 12TB NAS crashes it every time. Anyone have any suggestions for something designed for larger jobs?
