Backup Exec 2012 duplicate to tape SLOW !!!!!!
Hi,
I have 4 BE3600 R2 Appliances and 2 MSL2024 accross 2 sites.
I have configured BE2010 to backup Exchange 2010 with GRT and duplicate to other appliance and finally duplicate to tape.
Now I see that BE runs a job where it backs up the Information Stores and after that it runs 2 jobs (?) at the same time (???): one on the MMS and one on the CASO.
Every week duplicates are made to tape, however this week the dupicate failed with error E0009444, source duplicate set could not be found.
WTF ? it is there !!! I can see it, I can browse it ... hell, I can even start it manualy !!!
So I start it manualy .... 900MB/min !!!!!
Tape drive is a LTO5, it should around 4000MB/min AT LEAST !!!!
Why is this so slow !!!!
I really start to dislike this release of the product, it is not living up to the expectation and the specs.
Regards.
Apparently there are some issues when a Job is created with the Client Side Deduplication option enabled.
After 5 or more jobs E0009444 errors starts to rain down.
Solution: disable Client Side Dedup.
The performance lag when rehydrating backups to tape is a more serious issue. I am waiting on a statement of Symantec about the "real" speed it should handle and wheather they tested this with LTO5 or LTO6.
