Duplicate backup job runs slow
Here are the details about the setup mentioned below.
BE2010R3 with sp2 and all hotfixes
Raws on win2003 sp2 64bit exch2007 server
We are first backing up the exchange data to Dedup folder and then duplicating it to tape as per our requirement.
The backup to dedup will complete in 6 hours or so and it backups up around 250gb because our db is around 250 gb in size.
Then when duplicate to tape starts it reaches upto 248gb in just 6 hours and then no byte changes but if we open the job activity the directories and files number changes/updates and the job will complete after around 5 hours. So totol time taken would be 11-12 hours for duplicate job
We tried to backup to B2D folder and then tried to duplicate it and it runs fine and duplicate job completed in just 4 hours.
Any reason why backup exec is behaving like this.
