Hi,
I've googled a little bit and I'm having a hard time to figure out
which is the best scheme for our needs.
First the info:
- We want to have weekly backups of 4 our servers:
- Exchange SBS 2003. For the time being, I just need to backup the
Storage databases, not the full system, so I'm actually able to recover
individual mailboxes.
- SQL Server 2005 and 2000 server. Just the database information.
- File share server.
- Virtual server, currently running Virtual Server and VMware
Server, but probably will run Vmware Server only.
Our idea is to create a full backup on Monday and create differential
backups in an external USB drive. Right now We won't make any rotate of
USB drives, but the idea is to take the drive on monday (before the full
backup) and rotate it offline.
Full backups one day a week and then perform incremental backups (or
differential backups - I've just seen a difference if you are backing up
Exchange - I guess is the same with SQL Server - differential backups
don't delete log files). However, my big concern is that if any of the
incremental backups goes wrong, you lose up to the only backup that was
good.
I was thinking of creating an incremental backup for each day in
respect to the full backup (not the previous incremental or differential
backup) so I can get individual differential backups.
Questions:
- Is it possible to access within the differential backup the files
that were created or modified that day without needing to restore the
full backup?
- What is the best scheme that I should use for each of the servers
(differential, incremental). Is good my approach of creating an
incremental (or differential) backup from the full backup of monday?
Thanks
Miguel
