Lets say my NAS (DS620Sslim) has 40TB of data on it at capacity (6x 8TB in SHR1). It has 2 USB ports on the back.

Can I connect two external 20TB USB hard drives to it, and have Hyper Backup do a daily 20TB backup to one USB hard drive and another daily 20TB backup to the other USB hard drive?

I don’t need the software to decide how to split the 40TB, I can do that manually if necessary by selecting the folders and the backup destinations.

Basically want to know if Hyper backup supports two USB hard drives at once,since my 40TB of data that needs to be backed up exceeds the 20TB maximum capacity USB hard drives I can buy.

Not interested in buying a second NAS for backup at this time.

If Hyper Backup can’t do this is there any other software in DSM that can? Or maybe a better option/method?
