Hmmm interesting
can you tell me a bit more about your hardware ?
i'm facing a performance problem with a F50 with 2 ibm's 3590 (14 MB/sec,
10 GB/tape) and an ATM 155 Mbps network connexion (thus 14 MB/sec too).
some guys want me to have backups processed in two steps (client -> disk
pool via network, then, when finished, internal disk to tape migration on
server), what needs considerable amount of disk space on the server, while
i believe concurrent backup and migration is as fast (that is, using the
disk pool as a buffer), and even that a backup directly to tape would not
take that longer...
so i'm interested in some details
tia,
