We backup our SBS 2000 server / Exchange using Veritas Backup Exec (yes I know its old now!).
Currently we backup at around 11:00 pm, which takes around 3.5 hours to complete.
The server has a Sony AIT 1 tape drive (SCSI 160) and backup totals around 26 GB including Exchange emails and data.
The issue we have recently is that people who log on to the system remotely using Outlook Web Access appear to be doing so after 11:00 at night when the backup is running! This has caused some backups to fail due to changed emails in Exchange etc.
Should I be disabling OWA and maybe even SMTP to stop any changes to emails while backing up?
Currently we use a PRE/POST job in Backup Exec that stops the VSAPI virus scanning of Exchange (advised to by most Anti Virus companies).
I could incorporate many other jobs to stop services into this, but is this necessary? I know Veritas Backup Exec is supposed to do an "Online" backup of Exchange but is this really reliable considering the data is changing (new emails coming in, being sent out etc).
Can someone recommend what the best services are to stop whilst performing a backup of an SBS / Exchange server....
Also should we be looking at replacing the tape drive with either a new AIT 3 or Ultrium LTO drive? What would be the best to use nowadays?
We will look to be replacing the server soon, so I should imagine an External drive would be best which we could utilise also on the new machine.
Appreciate any comments.
