Dear Networkers,

Currently we use DLT7000 drives and are looking into choosing a new generation
of media. Obvious choices are LTO SDLT and AIT. The idea is to slowly start
moving one of our pools. Others will follow as we buy more drives.

Backup server Solaris 8 / E450 / 2 400 Mhz cpu / 1Gb mem

Our backup rate is approx 400 Gb per night  over 350 clients both servers and
desktops. Network infra structure is 1G backbone , most desktops and all
servers 100 FD.

Currently no capacity problems on the server side as the network cannot
deliver more data than the server or the tapes can handle.

Experiences with interoperability of LTO (drives by diiferent vendors) would
be nice.

We do see that AIT is cheaper, but heard stories of increased head-wear due to
helical scan technique.

The plan is to do backups to disk first and then spool them to tape.

Any ideas are welcome,

Maarten
