Server backups

Backup Server to USB drive it's a worst idea.
If you have a Rack you should find something like NAS
Sometimes NAS are expensive but you can try to find Buffalo NAS (used) and replace HDDs)

Then you can use Windows Backup software (build in) or purchase Symantec Backup Exec

USB is fine, but don't keep the disks at the location. The idea of good backups is to have more than one backup media which you rotate between, and remove from the site after the backup. Those backup media should be stored as far away from the server room as possible, for example in a bank safe. If they are in a rack in the server room where your server is located, chances are that if something happens to the location (flood, fire etc.), you loose both the live data on the server and also on the backups.

Also, after the backup is done, the disks or whatever you are backing up to should be brought offline, so no malware that may have infected the server has a chance to also compromise the backups.

Thanks everyone,

I think I steered everyone in the wrong direction. On the server I have now, I use Backup Assist and back up five days a week to five different drives, then one disk on Saturday with differentials, then save that drive to home. The server is upstairs (difficult to floor), rack and NAS drives downstairs (difficult to have fire). I put one drive a week in a safe drilled into the basement. I back up my data to Jungle Disk. And, modular backups for four super important apps to a backup. Too much data actually.

I think when I said USB 3.0 drive I confused people. I just meant large drives in a case that can be rack mounted. I use USB 3.0 external drives which I unplug after doing incremental backups due to the possibility of ransomware.

Ironically, and I apologize for this, but it's ironic because I had really bad experiences with NAS drives which happened to be Buffalos. Maybe SAN is better and maybe I am just bad at networking, but I constantly had trouble keep the UNC.

I will look at Cloudberry. I guess my question was, and I apologize for not being clear is that right now using Icy Docks, it holds eight 1 TB drives. Those are my five days of the week, plus a few other things.

For the new server, I want to simplify things. Since the new server will be downstairs, I wanted two backup drives for every other day. I wanted to put them on the rack, and I wanted to connect them via USB 3.0. I just don't want to have them networked via Ethernet.

I think I confused everyone including me with the USB. I also feel kinda stupid bragging about my backup system. I guess I was just trying to show that I know a little about backups. Sorry.

Anyway, QNAP and Synology seem to have combined Cloud and Local backup more in my price range. Thanks for everyone's help.
