- We're running a site with 3 SCO 3.2.4 machines and 1 Ultrix 4.3 machine
- having a total of approx. 10GB of disk storage. On the SCO machines we
- use Emerald Systems DAT1000 1.3 GB DAT tapedrives connected to an Adaptec
- 1542B controller. As software we use Lone-tar which supports multiple tape
- drives. This all works perfectly for us doing a master backup once every
- week, and incremental backups on a daily basis. On the SCO machines we
- tried the Emerald DAT 2000, but with no luck - it made the Adaptec barf and
- halt leaving a crashed file-system and no backup - so I cannot recommend that.
-
- On the Ultrix system - we use the Emerald DAT2000 and the dump command
- on a non-rewinding device, using the same backup scheme as we do on SCO:
-
- A weekly master and a daily incremental.
-
- Hope this helps.....
