Full backups if you can

by gjc In reply to Determine your tape backu ...

Having done a few Disaster Recoveries over the last 25 years, I firmly believe that full backups every night are the best way, if you can. Recovery from incremental/partial backups is slower, and being more complex, adds the element of human error. I usually set up backups for Mon-Thu, Fri 1-4 (Friday of the Month), Jan-Dec, and the December tape is kept forever.
This makes DR and file recovery easy.

Full backups nightly are the way to go

by AV . In reply to Determine your tape backu ...

We do full backups every night on our 7 servers. Incremental backups proved too tedious to restore from. We use 2 backup units - a DLT and an older DAT drive so that the jobs finish no later than 8am. The backups are verified every night as part of the scheduled backup job. Random restores are performed on occasion to check tape integrity.

Tapes younger than 60 days are transported to and from the office every day as needed (if not needed, they are stored in my house). After 60 days, backup tapes are written over except for a weekly Friday tape that is sent off-site to a climate controlled vault in a storage center for permanent retention.

Older backup units are also retained so older tapes can be restored if needed.
