hi everybody,
as promised, here is the writeup of replies to my inquiry about system
backup devices. the *s denote the number of people mentioning the
respective devices :
general :
-------
- one user found that tapes (in general) are not reliable for long
term storage, but should be o.k. for backups (*)
- one user pointed out www.transtec.de for good prices on DDS-4 systems
(*)
about different media :
---------------------
- DLT tape is highly praised, albeit expensive (***)
- DAT (at least the older ones) was reported to be problematic
from the hardware side (brake down of tape drive and frequent cleaning
required) (**)
seems like other people have been content with DDS-3 and DDS-4 (**)
- An ecrix VXA (www. ecrix.com) system was reported to be relatively cheap
(as compared to mammoth) and very dependable (*)
- one user is in the process of switching everything over to
a backup server, doing all the backups via ethernet on an array of
80Gbyte hard discs. thanks for re-emphasizing the difference
between backup and archiving ! (*)
should i get more replies, triggered by this one,
i'll post again. thanks, again, to everybody who replied.
