Syncing two hard drives in Debian

[VinylxScratches]

What would be the best way to sync two hard drives both on separate USB?

Unison worked good for me, i use it to sync a directory on a thumb drive with a directory on an external hard drive, and a local directory.

gotta have all the permissions set the same, however.

If both are going to be plugged in all of the time then a cron job running rsync should be fine.

They won't be. One hard drive probably will, the other will just be plugged in once a week to make a backup copy.

rsync would still be your best bet. Just create a little script with your rsync command and run it manually when you plug in the usb drive.

Or if you wanna get fancy you can try to figure out how to get udev to run it for you when you plug it in, but that can get pretty hairy.

yeah, this is why i used unison. click click click and it sets up what you want done and saves it, and one click to sync. and it easily syncs back and forth to cover changes between both devices. the only issue that bugged me was permissions, but that was because i had a fat32 flash drive i was syncing with my /home directory
