Try;

[ "$1" = "offlinebackup" ] || [ "$1" = "onlinebackup" ]

I believe this is actually prefered form, according to PSIX.
There are problems with the complicated precedence rules of 'test'
(mixing up operators with operands) but it becomes a rats nest
after more than about 4 arguments. You never need to use -o or -a
with this form and it saves a lot of problems.

Try PSIX IEEE Std 1003.1, shell & utilities - "test", I don't have a URL but a search
with find it. Also a very good one is the freebsd man pages at;
