Backup tape rotations

well, the first question is what email system you have?
the second is: what do you mean one year rotation? having records of all emails for a complete year? if so, you need 365 tapes,
since a mail that was deleted at the 23's day,
and overrided in the 245's day, wont
be backed up in the 246's day.
I am not sure this what they want. I would suggest:
3 daily cycles (Monday-Thursday),
3 weekly cycles (Friday's),
3 monthly cycles.

About the my first question, you can buy an
exchange aware backup solution/agent.

Good Luck.

No comment on contacting Veritas for answers here, "been there, done that!".
You might want to question why legal wants to archive a year's worth of e-mail. Security guidelines I've seen usually recommend 3 moths at a max. This is because e-mailshave been, can be and will be used against a company in law suites. If you have a policy that says you don't archive e-mail more than 90 days, then the backups cannot be subject to subpoena. Check any of the plethora of security policy templates on-line. There will be an added side effect to this in that you will not need as many tapes. Your legal beagles should be able to understand this strategy.

This is my yearly backup rotation. Keep in mind sat and sun I have very little network traffic.

Mon through Fri Incrementals-- Stays onsite and overwritten the next week.

Sat Full Backup -- stays onsite for one week until the next weekly full backup. Then goes to a safe deposit box for one month.

Sun once a month -- Monthly Full backup This goes directly to the safe deposit box and stays there for one year.

If you want a more detailed plan e-mail me with more specifics.

If you want to able to restore from a certain day 9 months ago you do need 365 tapes depending on how much you backup. This not recommended!!!! With this plan you'll be able to restore any certain day within one week. Any certain week within 4 weeks. and any certain month within 1 year.

Whatever your plan make sure you make it corporate policy and publish it to everyone in the comapany just to cover yourself.

If you just want a record of the E-mails, I would just enable full logging, so you log the entire message, to a drive with space and then back that up and clean it up regularly. Otherwise you will either have to backup the mailboxes (very slow) or restore the entire exchange database to recover mail. You could also turn on the no delete option that saves mail even when the user deletes it, but that would be a hassle beyond a month.
