Is it safe to use a network share as a BUP_DIR?

[Bruno Bigras]

Hi,

Is it safe to use a network share (CIFS mounted with autofs) BUP_DIR with bup?

What happens if the network share or the network goes down while a "bup save" is taking place? Will it resume gracefully the next time "bup save" is executed?

Thanks,

Bruno

It should be okay. bup is pretty resilient and only creates new
packs, it doesn't rewrite existing ones. However, I'd still suggest
using something like 'bup save -r /path/to/cifs' instead of actually
putting your BUP_DIR there. That uses the bup remote protocol and
works the way bup is supposed to work: BUP_DIR is local (and thus very
fast, for the high-bandwidth activities) and the remote dir contains
the actual backup.

Have fun,

Avery
