We currently host an environment where we have company common drives, roaming profile folders and user shares hosed on a Windows Storage Server 2008. On this server we run shadow copies 4 times a day to improve the number of backup points we have for our users.
Here's the problem. The users that work on terminal servers (Windows Server 2008 r2) experience hangs and application errors around the times of two of the copies. These are different companies but in in excess to users experiencing that everything hangs for a short while we've also have seen them report hang ups and crashes in programs that use files from the common drives, user profiles or users shared folders.
Is there some way to optimize shadow copies to not interfere with daily operations? Are there best practices on file servers that run these kinds of tasks? We very much want to avoid switch shadow copies off since our users are aware of the feature and expect to be able to reverse to backups taken every few hours.
