Single item recovery doesn't affect the DAG, but it allows users to go back and retrieve items that were previously deleted. Think of it as the Exchange 2010 equivalent of DumpsterAlwaysOn, but with steroids.

I'm giving a talk on this at Exchange Connections in Vegas at the end of October - please attend! (To Backup Or Not To Backup - That Is The Question! - that was my working title, they may have renamed it.) As long as SingleItemRecovery is enabled, your Deleted Item Retention and Deleted Mailbox Retention are set to reasonable (for your company) values, and you have a DAG copy in a "safe" location - the need for backups (other than making you feel "warm and fuzzy") is arguable. Dependent, of course, upon specific statutory needs not covered here. Regards, Michael B.

If you do backup to disk/tape, what type of retention do you have? And, yes, I know the retention issue is extremely subjective, depending on legal requirements, etc. Just curious. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
