Does anyone have any recommendations for good backup software? My use case is pretty simple. I have an external usb drive I want to backup to every so often. Both the source and backup drives are 8TB capacity (I’m not even close to using the full capacity yet)
Normally the backup drive is left unplugged but I want to be able to plug it in run the backup software to copy across anything new then unplug it again for storage.
Simple file backup (not looking to do a full bootable OS drive backup or anything)
Hey, I'd recommend taking a look at Syncthing. It's software that runs locally, and you can configure the synchronisation to occur in a unidirectional flow instead of bidirectional. I.e. configure it to only synchronise data from the source drive to the backup drive.
Hope this helps and all the best!
EDIT: As pointed out, Syncthing is more suited to syncing data between two or more devices so may not be the right solution for OPs use case.
