From: pmaglin...@scvl.com To: exchangelist@lyris.sunbelt-software.com Subject: RE: No tape Exchange 2010 Date: Thu, 24 May 2012 14:51:36 +0000 We were told that if we were running at least a 3 server DAG and that one of the databases lagged behind the other two at a DR site, that tape backups wouldn’t be necessary. The lagging database was in order to recover in case the database became corrupted and replicated. I’m not that trusting. I still believe in good ol’ fashioned tape backups. I think of it as insurance. If you think you can get by without maximum coverage you can pay less of a premium. -Paul From: Young, Darren [mailto:darren.yo...@chicagobooth.edu] Sent: Thursday, May 24, 2012 9:13 AM To: MS-Exchange Admin Issues Subject: No tape Exchange 2010 Is there anyone here running Exchange 2010/DAG and not doing tape backups? In our primary site we have 4 mailbox hosts with an active and inactive copy of all DB’s, DR site has 2 hosts with inactive copies of most DB’s. We have about 8 TB of mail in the primary site and another 6TB in the DR site. 6500 active mailboxes, 15% quota at 2GB (faculty & staff) the remainder at 1GB (students). We then have an additional 20,000+ 20MB alumni mailboxes that we don’t include in DR. Tape backups in the primary site are getting, well, rather unwieldy. We currently use TSM with the Exchange TDP to spin copies of the inactive DB’s to tape at the primary site. We’re considering adding a lag copy in our DR site to cover DB corruption risk. As far as we can tell, the only reason we still would need to spin to tape is to recover a deleted mailbox. We’re currently hanging onto those for 30 days in Exchange and in theory could extend that period to cover that risk. We don’t offer item level recovery for users from tape, we hold deleted items for 14 days so they can do it themselves. Looking through our tickets we see that we’ve only done 3 restores from tape in the past 6 months, 2 for “accidentally” deleted mailboxes and 1 from a subpoena. All three of them were over the 30 day Exchange deleted mailbox policy but within the 90 day window we keep backups in TSM. Looking for any thoughts from other people not spinning Exchange 2010 to tape anymore.
