Hi John,
I had a similar situation with Exchange 2010 TSM DP backups and the
reason was the VM had been Vmotioned from one ESX to another. Lan speed went
from 1Gbs to 100Gbs. You might want to check this.

Thank you Chavdar Cholev and Jeanne Bruno for sharing. I forgot to tell, we do
skip the integrity check, and there are only passive Databases on the server.
Are your backups going to TSM server or to a local storage? Im interested
either way.
Best Regards,
John

Betreff: Re: [ADSM-L] Exchange Backup with Flashcopy Manager EXTREMELY slow We
have ~ 2TB full exchange backup and it takes ~ 20 hours. There is exch db
consistency check before backup which takes considerable amount of time.
It can be switched off... but it is not recommnded

Hello fellow TSM Admins!
I'm struggling with Exchange Backup which over the course of the last
few Days (mainly since the last full backup this weekend) takes about
3-4 times as long as before.
We have Exchange 2013 DAG with 48 Databases and a dedicaded VM to do
the Backups (Flashcopy Manager 4.1.1, Backupdestination=local, on an
IBM V7000 Storage).
Right now even an incremental backup of 1 database takes ~12 minutes,
but the volume is only 30GB big and has only 5GB (5000 x 1MB Files) on
it. Two weeks ago this would only take 3 Minutes.
A Full backup takes about half an hour (so I couldn't even complete a
full backup for every database in one day). I also tried to
full-backup the same database twice right after one another, with no
difference.
This can hardly be normal, can it? Has anyone had the same problems
and maybe could point me in the right direction?
Also it would be great if anyone could share how much time their
backups take...
Best regards,
John
