I realize it works for some people. It's not for me. Here's why: 1) They take a loooong time. At my last position, the priv.edb on several Exchange servers was huge with several mailboxes exceeding 2GB. Backup windows of 'July' is not acceptible nor necessary. 2) Brick Level break SIS in the process. At a previous employer we had an SIS ratio of 4 (lots of little daily cash spreadsheets and the like getting sent to DL's). This means that a BLB backup uses as much as 4 times the total tape. Now I need an autoloader to take care of the boxes of tapes required each night. 3) You can't perform a full server restore to point of failure with brick level backups. You have to actually perform additional full online backups as well to allow for full disaster recovery. More tapes. More time. More money. 4) A restore of several mailboxes from BLB's will cause the store to grow because of no SIS. If my SIS ratio is 2 and some disaster leaves me with only brick-level, my restore will double the size of the priv. 5) The redundant backups for brick level lower the overall performance of your exchange server as backups compete with users for CPU cycles and disk reads. It is also additional and unnecessary wear and tear on tape drives. 6) Brick Level Backups do not backup items in deleted item retention. As my users (for email anyway) have always been of the educated variety, they know and use deleted item recovery as needed. 7) A restore of a mailbox is seldom needed. (Probably the only instance is inadvertant deletion by an administrator in Exchange5.5) With deleted item retention set to a reasonable 30 days or so, and with deleted mailboxes retained in Exchange2000, brick level backups fall in the category of a waste of time and resources. 8) Backups should not be a helpdesk support option. They are a disaster recovery requirement. With all that tape and time, the convenience of having kanee restore my mailbox is so simple I can be more careless with my email. I can always get my info restored. 9) Yes, it's true. For me, I have only done this using ArcServeIT. Because of comments here in this and other forums, CA took the Exchange agent back to the lab and did some more fixing on it. For me it was too little too late. Basically, BLB's are not perfect. Data is not perfectly recreated through the restore process. Problems included header info missing, digitally signed emails corrupt, attachments missing. 10) Many, many more reputable and experienced people have shared their horror stories over and over in this and other forums and newsgroups. So much so that I was relieved to learn in 1998 that it wasn't just me that felt this way. The people that have expressed this opinion I hold in high regard and certainly owe it to myself to try to understand why the concensus is for or against something. 11) Microsoft provides the utility ExMerge which can be used to backup a single mailbox to .pst if necessary. I use this as the last step before deleting a users mailbox after (s)he have left the company. It is a simplified, granular alternative for certain circumstances.
That's all I can think of for now. There are lots of other totally unnecessary things I do on my networks that I'm sure other people would scratch their heads at.

The mapi32.dll file is very sensitive and reports errors on messages as cannot open and thus will show the status of backup as failed. There isnt really much you can do about this, except ask the user to delete the message its referencing in the error message from his mailbox and empty it from deleted items. I have spent some time with veritas and they point fingers at microsoft and i spoke to microsoft and they point the fingers back to veritas, veritas knows of this issue and they say they are looking at a solution and should be out in the next build for backup exec8.6, i know you use netbackup so maybe you should look into their next build for netbackup. Even though this error pops up and the overall status of the backup job shows up as failed, the backup in actuality is successful, you can restore the users mailbox and the only thing missing would be those messages that it reported as corrupted or cannot open. So dont loose any sleep over this you are fine. dONT LISTEN TO PEOPLE TELLING YOU NOT TO DO BRICK LEVEL BACKUPS, ITS ABSOLUTELY NECCESSARY TO DO BRICK LEVEL BACKUPS, IT WILL SAVE YOU SO MUCH HEADACHE AND HEART ACHE LATER..TRUST ME. -----Original Message----- From: Kulwinder [mailto:[EMAIL PROTECTED]] Sent: Monday, June 10, 2002 10:31 AM To: Exchange Discussions Subject: RE: Veritas Netbackup error on MSX 5.5 Thanks for the info. > Well then, might i suggest, as Andy and no doubt other admins would > recommend, that you should stop doing BLB's.
