The main working difference between ext3 and 4 is file size, ext takes a
massive file, ext3 does not, but there are other googleable differences!
I would agree usb is not the ideal method of transport (USB3 might be okay
but I have no real experience other than for laptop storage), maybe you
might look at a network attached device, I like the netgear nas boxes, I
would NOT recommend any of the older lacie disks.
Kind regards

Hello Folks
What's the current thinking regarding the best filing system to use for an
external USB backup disk?
My client has two backup disks, formatted with ext3, and swaps them over
from time to time. They are mounted via autofs, and rsnapshot creates the
backups.
Occasionally something gets stuck -- perhaps because the user unplugs the
drive in mid-backup.
That happened today, and currently I've got fsck running -- so far it's
found illegal blocks in a couple of inodes, and lots of multiply-claimed
blocks.
Is ext3 still the best choice? Are other filing systems more robust in this
situation?
I realise that no filing system can be indestructible, but I thought I'd ask
in case this turns out to be an 'opportunity' to change the filing system.
cheers
Chris

That's a bit like asking which single engined aircraft is best for flying
the Atlantic. You talk about "your client": if they are a commercial
organisation, and they think that backups to a USB disk are a good way of
doing backups, I suggest that they need educating.
First question to ask them: When you did your last test restore from
backups, did you experience any issues?
