Backup Exec *.dr Files - When are they updated, and is there enough point to them?
Hi all, when reading about the IDR option I noticed that the *.dr files are only updated when an entire backup of the server is done, without any exclusions - does this eman I am forced to backup absolutely everything, on all partitions, before the *.dr file is updated? Is it not only enough to backup the entire C: drive? The reason I ask is because when looking in C:\Program Files\Symantec\Backup Exec\IDR\Data I've noticed that the *.dr file for the server in question is being updated (according to the date modified) after every backup, even though we don't backup any full partitions at all currently, not even C: - all we back up are fragments of D: and F:, the system state, the exchange info store, all SQL DB's, the utility partition and the shadow copy components.
Ultimately what I'd love is to have a tape containing the entire C: drive, and just the important areas of all other partitions, and the other obvious important parts such as system state etc, and be able to restore this tape using IDR. I'd probably perform this backup job weekly, so our current weekly backup would jsut be extended to include the C: drive, and on Monday I'd come in and copy the *.dr files to a USB stick and move offsite.
One other question - I'm surprised at the fact you have to manually copy *.dr files onto a removable drive every single time a full backup is completed - this seems like a lot of legwork, it almost seems pointless as from what I can tell the only benefit to having the dr files is that you have an up-to-date list of backup catalog's, and the alternative is that you simply manually select the tape to restore from - is it not much easier to forego copying to dr files and just put up with having to manually choose the backup set to restore? Is there any alternative that the dr file brings?
Any suggestions on peoples own disaster recovery stratergies or experiances would be very welcome indeed :)
