Backup to TWO external USB Hard Drives ONE at a time for off-site storage
So as the subject says. I'm succesfully backing up the NAS every night on schedule to ONE USB drive at a customer's premises. After speaking to the customer the question was: Can we add a SEC...
I suggest creating a single backup job that specifies the USB port as the destination (and not the drive). There are some firmware versions that won't allow this selection if you have the drive inserted - so you might want to eject the drive first.
I don't do backups this way, so you will want to test it to make sure it works as expected.
If you want to prune out deleted files on the NAS, you can specify rsync as the protocol, and specify the source as remote instead of local (using 127.0.0.1 as the host address). Then you will get incremental backups, and you should see an option to delete files not present on the source.
FWIW, if you specify a local source and destination, the backup job will use linux cp, not rsync.

StephenB, I think this is exactly what I want. It's unfortunate this is an untested solution as you specify, because going to the customer with "this might work", and charging them for the external drive and some on-site labour setting it up could back fire, but your solution is most definitely the exact sort of thing I want. The customer simply swaps drives out once a week (or month whatever they decide), without having to know any nitty gritty.
Can someone chime in and confirm they've done this with the 4.x series firmware on the model I mentioned and it works? Sounds like it's worth a try anyway as the logic is sound, but if someone's done this and it work by all means chime in for customer reassurance.

I just want to clarify a couple things. I don't work for Netgear, so you aren't my customer - I'm just sharing an approach which I believe will work. This is a community forum, not just a netgear support forum.
Also, I have no idea if Netgear tests this particular solution or not. I haven't tried it, because I've chosen to use NAS->NAS backup myself, not USB
