I have the following options selected:
Destination
Device and Media
Overwrite Media
Write checksums to media
Settings
General
Backup method for files: Full - Backup files - Reset Archive Bit
Verify after backup completes
Compression type - Hardware
SQL
Microsoft SQL Server
Backup Method - Full - Backup entire database
Exchange
Microsoft Exchange
Exchange server backup method - Full - Database & Logs (flush committed logs)
Mailbox backup method - Full - Backup messages - Reset archive bit

My backup is scheduled for 10:15 PM every weeknight when there are no users on the system. Any ideas as to why the Exchange Mailboxes take so freaking long to backup??

The database never stops working. The Store backups, you'll see, are processed quickly.

The mailbox level however is very long. I had to stop doing them because they were taking 30+ hours. I have to revamp my backup schedule and round robin the bricklevel. I haven't seen it process quickly since we were only 20 users. Now at 70, it takes ages.

Also, do you have a blackberry server? I think this may add to the slowness, though I haven't proved it yet.

 

[rodentcentre]

So there is basically nothing I can do to speed this up at all??

One thing you don't say is if you have the agents for SQL Server and Exchange.

(BTW-it's not suggested that you use BE to backup SQL Server. You should use the SQL Server BACKUP commands to do backups to hard drive and then use BE to copy those backup files to tape).

Not that I have found. But I am open to suggestions.

Because I get asked weekly for emails which were lost or deleted. It's getting to the point where I am pricing an Exchange Only backup system, But letting the mailboxes take 3 days to backup isn't a viable option either, I suppose.

SQLBill -

I do have both SQL and Exchange agents installed. I am anal so I do have SQL jobs created to backup the logs and all of the databases on the server as well as the Backup Exec jobs to backup the database.

Rodentcentre –
In the E2K Manager in the Private Info Store Properties, check the “Limits” tab. You can save “Deleted” items and mailboxes for a number of days. After this is set, you don’t need to do a brick level save every night. Just on the weekends only. But keep doing the Data Stores nightly incase of a disaster!

 

[SQLBill]

If you are using SQL jobs to backup the database and the LOGS, DO NOT use BE to backup the database also.

It will 'ruin' your LOG backups. The log backups are since the last full backup. When was that? The SQL full backup or the BE SQL full backup?

Have you ever tried to restore a database? If you are doing backups both ways, you may have problems restoring. Like I said above, which log backups go to which full backup?

Rodentcentre,
The bricklevel backup will allways be much slower the a OS or store backup. Your TP time of 49 MB/min does not seem that bad for a DLT drive, but it does seem slow for a SDLT drive. I use a HP SDLT 160/320 internal drive on a ML370 G4 2 Xeon 3.06 CPU's and 3 GB RAM. All HD are SCSI 15K HP drives and get 120-140 MB/min for Brick level and about 1500-1900 MB/min for store.

Have you looked to see when your daily Exchange server maintainence is set to run? This maybe slowing down your backups. I changed the maintainence schedule on my Exchange server to run 2-6am. My Exchange backup starts at 7:30pm and takes about 4 hours to finish. I am doing a Bricklevel of mailboxes, stores, system state and OS for a total 64 GB including verify.
