ms exchange5.5 mapi veritas backup for win2000

Pachoo,
Are you remotely backing up 5.5? if so, do you have the remote agent installed on the exchange server? This can dramatically improve backup times.
Also is it just the mailboxes your backing up, or are you also backing up the information & directory stores?

Mailbox backups are slow by nature due to the use of MAPI protocol which was not designed for speed or server type operations. MAPI has to enumerate every single friggin mail message one-at-a-time. It is SLOW! I have never seen a throughput rate over 70Mb/min in every client I have worked with.
That said, you may be able to up that throughput rate by disabling OUTBOUND email antivirus scanning. If you are using Norton Corporate on the Exchange server, then you need to know about VAPI vs. MAPI. When Norton is using VAPI to scan email during a backup, it slows Backup Exec way way down. Here is some helpful info on this:
Change from VAPI/MAPI combo mode to MAPI and then back to VAPI/MAPI:
Backup Exec slows down with Norton AntiVirus 2.11 for Microsoft Exchange when backing up Microsoft Exchange 5.5 mailboxes
and reports messages as corrupted.

"You are running Norton AntiVirus for Microsoft Exchange (NAVMSE) 2.1x and Veritas Backup Exec on your Microsoft Exchange
server. After installing NAVMSE, the backup takes longer to complete.
Solution:
Lower the Microsoft Exchange OpenRetryDelay from to 2500 from 5000 milliseconds by using the following steps.
CAUTION: We strongly recommend that you back up the system registry before making any changes. Incorrect changes to the
registry could result in permanent data loss or corrupted files. Modify only the keys specified.
To edit the registry:
1. Click Start, and then click Run. The Run dialog box appears.
2. Type regedt32.exe in the "Open:" field, and then click OK. The Registry Editor opens.
3. Navigate to the following subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\VirusScan
NOTE: If the VirusScan registry key is not present, then the antivirus API is not in use or has not been enabled on the Exchange
Server.
4. Click OpenRetryDelay (to highlight), click Edit, and then click "DWORD...."
5. In "Data," click Decimal under "Radix," and then type 2500 as your entry.
6. Click OK.
7. Click the Registry menu, and then click Exit to close the Registry Editor.
Some more info such as TrenMicro's ScanMail antivirus:
• Disable outbound email anti-virus scanning during backups.
• Disable email anti-virus scanning during backups: Try using a pre/post job commands-to-run to disable then reenable antivirus
services during the backup.
How to call batch files for pre/post job commands from within the Backup Exec GUI:
• Disable TrendMicro’s ScanMail "Realtime Scan Service" or "ScanMail_RealTimeScan" service during backups.
• Enable TrendMicro ScanMail’s "Incremental Scanning" to scan only the new emails, thus saving time and resources.
Finally, consider these alternatives and tips:
Deleted Item Retention
If you're running Exchange Server 5.5, one alternative is to upgrade all your users to Outlook 97, version 8.03 or later (including
Outlook 98 and Outlook 2000). This version is the first one to allow access to Exchange 5.5.
Set the retention time to something long, say 30 days (you can use even more if you have the disk space). Show your users how to
recover deleted items (it shows up as a menu item in Outlook, when viewing the 'deleted items' folder). This is the best, since you
don't have to do anything. The users do for themselves. Exchange 2000 does this by default for 30 days and includes the ability to
restore not only deleted mail messages but also entire deleted mailboxes.

set the alternate delivery to their boss (or someone else responsible), put the leaving date in the notes field and mark it hidden.

I'd be happy to send you the links in an email if you like. Just reply-post with an email address. (Their links are so friggin long, its no wonder they didn't make it.)
Thanks,
