I am just starting using the Veritas Backup Exec and need to get a good stratagie in place. Knowing how important it is to have a good system in place, I want to get off on the right foot. My office only has one server with RAID 5. My tape drive is large enough so it can save everything on one tape uncompressed.

If I have left out any information that would be helpful to answer this question better please let me know.

Thanks,
Dean

Assuming that your tape drive is not only large enough but also fast enough to do a full, uncompressed backup in a reasonable amount of time (i.e., less than 4-5 hours), you have an ideal situation for a "best case" recovery from backup if you need to. Just set up your system to do a full backup every night. Then, you don't have to worry about differential or incremental backups. I would, however, set up a media retention scheme to ensure that your tapes don't get re-used too quickly. My recommendation would be to have 4 daily tapes that have a retention time of 1 week, and 5 weekly tapes that have a retention time of 4 weeks. That way, you always have a number of backup tapes that you can restore from, in case one or more are not viable.

we use 2 diff methods,

1, 100gb raid 5 servers are backed up in full each Monday to a multiloader DLT, then incremental for the rest of the week.

2, 30gb raid 5 servers are backed up in full each night.

In each case, we cycle the tapes for4 weeks, and make a monthly full backup tape that is kept indefinately

Hi,
You should consider to backup every day full backup on a different media and for the last working day of the week use 4 different medias so you always have yesterday's backup and 1,2 and 3 weeks before.
