Still it's an important reminder about actual _access_
to backups. Of course it's very comfortable to access
all the backup media without manual (human) intervention,
but it can be dangerous. Imagine a situation like what
Cryptolocker malware usually does: It encrypts anything
it can access, and if it can find the backups, they will
be useless in any attempt to restore the system. I'm sure
it's more complicated to encrypt tapes (in an ATL) than
disks, but it's still dangerous when they can be accessed
"too easily".

Exactly, and there is no proprietary (and undocumented)
file format involed, or manufacturer-specific connectors
and access protocols. This is unimportant as long as
everything works as expected, but it may become essential
in a worst-case scenario.

On-site and off-site method - where off-site actually
means "somewhere else", instead of putting them next
to each other. ;-)
