Back-up question
Hi
We recently bought Veritas Back-Up and I want to use it to do a full back up once a week, and then just back up the changes to the files everyday. Then every weeek I will change the tape.
That's two jobs:
*New tape goes in every Friday.
*First job = full back-up, overwriting anything that's there. This be on Saturday, when no-ones here.
*Second job, runs every day, Monday to Friday in evening, records changes. Do I use differential or incremental. What's the difference? Anyway, this job will always append.
Come Friday, tape is ejected. This should contain one full back up file and five changes back-up file.
Does this sound good?

What way do you archive your backups, I would suggest that if you want to keep your backups safe from domestic and environmental hazard you should probably look into having a company backup tapes remotely. This way if anything does happen you will have a secoundary disaster recovery consingency plan should the owrst happen, their service often comes with collectiona nd delievery. Just something to look into.
No, it does not sound good at all.
Suppose you have a fire on Thursday and need to restore from tape???
Also, restoring of data could be a nightmare.
Backup the entire drive -- or critical files only if you prefer -- every day.
Keep one tape offsite.
That way you have FIVE complete copies of your backup

OK. Thanks so far...
Glenn, that sounds professional but it means a lot of extra work. Worst thing is someone has to go in the server room every day and change the tape. That's a problem because the server room is on another floor, and it needs a special security key to get in there. I'm not on site to do it more than once or twice a week. May be two tape drives?

Jason,
2 tape drives would be a great idea, and if its in your budget I would say go for it. That would allow you to keep the jobs on seperate media and you would have less intervention. But that still leaves the full backup on-site...

I would recommend differentials as the restore only requires the last full backup and the more current differential as opposed to incremental where you need the latest full backup and ALL incrementals till current.
I would also recommend keeping the full backups and differentials on different tapes. This way you know that once the full back is successful you put it in a safe place and it is there if you need it. You don't want to risk the differential backup compromising your full backup.
