We just recently migrated from Exchange 2003 to Exchange 2010 on W2K8 standard server 64 bit (not R2) with SP2 which went well with no real issues. After the migration we started a backup job of the Exchange database by using the built in Windows Backup which is Exchange aware but got stuck right after VSS finished doing a snapshot. The point we got stuck on is "Running consistency check for application Exchange" and we have been waiting for about 72 hours (more not less).
Specs of the server is as follow:
Dell PE2900 with Dual Xeon 2.5 GHz CPU
16GB of RAM
250GB OS Drive RAID1
900GB Exchange partition RAID10
450GB Exchange log files RAID10
We are backing up to a 1.5TB external storage connected via eSATA but we have never reached a point where the backup job starts to write to the backup disk so I am pretty sure that it is not a throughput bottleneck issue to the external drive.
We currently have over 430GB of log files (bunch of 1MB files) and 361GB Mailbox Database and growing. We need to cleared off the log files after a successful backup but we have never gotten to that point. I appreciate your comments and suggestions on this as we are running out of storage space due to ever increasing log files.
