I've found plenty of solutions for backing up PC's and servers TO a NAS box, but I can't find any thing that will let me back up data, on the NAS box, to removable storage.
I know that most NAS devices have built in backup to a USB drive, but that only holds a single copy and overwrites the last backup, This is certainly true for the QNAP devices that we use.
I need a solution that will allow me to take a backup of NAS shares, via a PC, to external storage, but appends the backups rather that just overwriting the last one. If it can be scheduled to run out of hours that would be a bonus.
Has anyone got any ideas?
Thanks
