They'd probably be better off hiring a "backup engineer" to go through all of their systems (end to end) ensuring full backups exist and work for everything.

Instead of backing up every system in isolation, have well though out backup/restore processes for all parts of their operation.

Saying that as someone who's done exactly this before (professionally, for mission critical places). ;)

eg:

· Inventory the systems (boxes, services, etc)

· Determine what each needs (package dependencies, etc)

· Create scripting (etc) for consistent backups

· Work out the restore processes

· Make it work (can take several test/dev iterations)

· Document it

And also (importantly):

· Have the ops staff perform the documented processes, to reveal holes in the docs, and show up parts which need simplifying
