Hi Richard Would you recommend a cloud archiving solution such as MS EHA ?

That would be my biggest concern: the absence of a backup to restore someone's mailbox from two to three months ago. There's backup for disaster recovery, then there's backup for user stupidity. From: bounce-9036114-8066...@lyris.sunbelt-software.com [mailto:bounce-9036114-8066...@lyris.sunbelt-software.com] On Behalf Of Neil Hobson Sent: 29 July 2010 09:44 To: MS-Exchange Admin Issues Subject: RE: Exchange 2010 DAG and backup options/recommendations. In addition to what has already been said, let's talk a little about your statement "a backup system isn't really required". What you're referring to there is Exchange native data protection and if you go down this route there are some very clear things that you need to consider. For example, the MS recommendation is that you have at least 3 database copies if you implement native data protection; you've said 2 copies per database in your statement. I don't know your environment, and I know it's extremely unlikely to happen, but could your 2 on-site buildings be taken out at the same time? Consider a 3rd copy somewhere completely remote. You say you're worried about database corruption - that's where lagged database copies come in, so you'd need to consider those (which will take your design to 3 database copies anyway). Also, what are you planning to do regarding single item recovery? That affects the users and your ability to restore in the absence of a backup. From: Pfefferkorn, Pete (pfeffepe) [mailto:pfeff...@ucmail.uc.edu] Sent: 28 July 2010 21:02 To: MS-Exchange Admin Issues Subject: Exchange 2010 DAG and backup options/recommendations. We are going to be moving to Exchange 2010. Basically we will have 14,000 users and will allow users to go up to 4 gig mailboxes. We will have 4 backends distributed between 2 on-site buildings for redundancy (power/network). We will also be deploying a DAG configuration with 2 copies per database. We are talking a ton of storage and the question keeps arising about backups. I've heard with the DAG deployment, a backup system isn't really required because of the database replication, but my mind keeps going back to the possibility of database corruption. Total data to be backed up could be 192 terabytes, so it's a large amount of data. I was wondering what other large shops are using for that type of data. Comments on backup strategies for 2010?
