Not sure about that...  ;)

Don't DAT. I have seen too many dead drives...

From recent experience with a NetBSD/Amanda backup server at work I can
heartily recomment Tandbergs SLR series (SLR5 here). Amanda
<> built cleanly from the package -- most of the
people reporting trouble on amanda-users appear to run linux =8>. The setup
currently backs up ~35GB of disk space.

If a DDS-2 drive (4G?) did the job for you until now I don't think you
really need DLT unless you want to do brute force full backups every night.
Even then, you still have sustain the data rate to keep it streaming - we
have a 2x i386 PPro Netfinity SAP R3 server at work that is incapable of
streaming its DLT.

Only drawback of QIC is that NetBSD's st(4) QIC support sucks... You have
to hack in "quirks" for contemporary devices yourself.
