In testing this with our original Exchange 5.5 deployment the brick level backup and restore takes up far more resources than your typical MS Exchange API backup. Let's say your Infostore on your 5.5 machine is 30gb in size. Your backup will probably exceed double that size because every mail box is backed up as a separate entity any items that are shared or any single item that has multiple pointers to it will have to be backed up every time it is referenced in an individual mailbox. Veritas Backup Exec and I believe Netbackup does have a brick level feature. There are a number of others but I don't have any experience with them.
Additionally, there are other products out there that will allow retention of deleted mailboxes for a pre determined amount of time. They do require integration into the Exchange environment and have to be managed. But that does not protect you in the event of total server loss or historical or legal requirements. In our 5.5 site and during our testing of our Exchange 2000 deployment environment it has proven to be far more beneficial to have 1 or 2 standby servers that are used exclusively to restore infostores for legal or recovery purposes.

If you are talking about the calendar and other little goodies including public folders, none do that except maybe CommVault. And, I do not think they can do the public folders. The thing that Veritas and Arcserver created are for marketing only and really are so slow you can only use it for a few select mailboxes. None replace the normal exchange backups that you have to do to be able to recover the exchange stores. I found out just yesterday that Exchange 2000 has a reserved area you can restore an information store to. Once you have done that you can truly recover a mailbox and its contents. This was Microsoft's answer to the problem. But, Exchange 2000 requires active directory and other hurdles to get there. However, my Exchange boys point out you must not put any mailboxes you might want to recover in the "base" information store because that one cannot be restored to the reserve area. That one has all the exchange specific extensions to active directory. Paul D.

There are only 2 other outside vendors that back up bricks, 1.) Veritas 2.) Arcserve2000 The only way to do individual folder recovery (i.e. Inbox, or Sent items, etc..) is to export to a PST file then back up that file. -----Original Message----- From: McMullen David E [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 16, 2002 10:43 AM To: [EMAIL PROTECTED] Subject: TSM and MS Exchange We are evaluating TSM here and a question came up with regard to TSM and Exchange. Will TSM backup and restore individual mailboxes? TIA David McMullen SMC/LAB Support 512.460.4559
