If Server A is compromised, then any other servers or shares it has write access to may also be compromised. Your backup target should support snapshots, or should back itself up incrementally to another target that Server A doesn't have access to.

It's an extremely oft overlooked problem in backup strategies. The one time you get bit or see someone get bit, and their onsite and offsite backups are all encrypted, you'll die a little bit inside.
