Hiya,
I know it's been discussed quite a lot regarding SnapManager for Exchange backing up DAGs - however I was wondering if anyone had some advice regarding the following setup:
2 Mailbox servers in production, 1 in DR over a LES (sub 250ms) which are all part of the DAG. 2 databases in the DAG, each production server has an active/passive copy while the DR server has the additional passive copy of each - So MB1 has DB1(active) and DB2(passive), MB2 has DB1(passive) and DB2(active) while MB3(DR) has DB1(passive) and DB2(passive).
What I'm aiming to get to is the DR server performing the verification and also having up to 8 weeks retention (as we have additional space on SATA), while the production servers purely have up to 1 weeks retention.
Currently we do 1 full backup at midnight which verifies then a few full backups without verification during the day along with FRPs.
I was thinking along the lines of having the DR server run the scheduled tasks using the -clusteraware option, but I'm not sure how to handle the different retention levels - would that be possible using the gapless copy feature to only have the production servers taking a copy backup? If so will that impact the log truncation in live?
Appreciate any advice 😃
Cheers
