When I’m running MailStore webinars, I’m frequently asked about file groups and how they work.
I’ve written this article to give you a good idea of how you can manage your existing file groups, how they can be moved around and what to do with those containing older email.
So what exactly is a file group?
We’ve seen a noticeable increase over the past few months in the number of customers performing Hyper-V backups using BackupAssist, so I’m hoping some of you will find it useful to hear about an issue we helped resolve recently.
The customer was running BackupAssist on their Hyper-V host system and had initially been performing a backup of the system state and some data which was working fine, when they added the Hyper-V guest machines though, it produced this error each time:
ERROR – A Volume Shadow Copy Service operation error has occurred
Since the introduction of Microsoft’s Volume Shadow Copy Service in Server 2003 it is common to backup the Exchange database in its entirety as part of a bare-metal backup job. This is a great way to deal with a disaster such as a hard drive failure where you want to recover a whole server, or even if you need to recover the whole Exchange database back to a point in time. The difficulty comes when you want to recover, for example just a single mailbox, or even specific emails. With a full backup, you are backing up the entire database which means you’ll need to recover the full database first to a temporary location, mount this as a recovery database, connect to it with a client and then extract the data. With a large database this could take quite a lot of time and resources to complete.
BackupAssist has a much easier, more convenient way.
