Backup's Running Extremely Slowly
We're having an issue with Backup Exec 2010 R3 (All Fully Patched) on a Server 2008 server.
We currently have 4 jobs in operation on this server - two SQL backups, an Exchange GRT backup and a Flat File backup.
The two SQL backups backup the databases from our two SQL servers and copy them to SAN for storage which are then backed up to tape.
The Exchange backup is the same, backing up mailboxes to the SAN and then transferred to tape.
The flat files backup, takes the majority of flat files from our main file server and the SQL servers (DB backups, word docs etc.) and then copies them to the same SAN ready to be transferred to tape.
The problem we're having is:
The SQL backup's and the Exchange backups all run at around 3000MB/minute or more and maxing out the 1Gb connection between the servers.
The flat file backup has an average job rate of 500MB/minute at best, and this is a backup that has to backup 420GB's of data overnight, but its doing this in more like 24hours+
We have tested the throughput between servers using standard Windows copy which all copy at around 100MB/s regardless of size, the only slow down comes when there are lots of small files (like the affected job is doing) where it slows down to about 70MB/s at worse but this is still 4200MB/minute which is a lot quicker than what Backup Exec is backing up at.
We have rebooted servers, turned off anti-virus completely and everything else we can think of but nothing seems to help.
Could anyone reccomend what we do next?
