[SOLVED] backups and Zimbra upgrades

[admin1]

We're a government outfit that needs to save backups for 1 year (in case of litigation, etc).
The Zimbra upgrade instructions state that old backups should be tossed out as they only work with version they were backed up from.

What is the Zimbra-recommended way to save backups that one might need after an upgrade?

My guess would be that you will need to keep a copy of the version of Zimbra for each backup around so if needed you can install that version on a test server and then restore that backup to the test server, but I have no experience with this issue.

Thank you, ArcaneMagus, for your response.
Maybe a backup system for this kind of scenario will be in Zimbra's future.
