Dont know anything about Netware,
Restoring always causes surprises the first time you encounter them,
speciaclly large amounts.
Note that several crucial aspects play a role here,
data may be multiplexed on tape that can cause a delay and if your data is
lots of small files that can cause a major delay aswell as your OS and the
disks are writing may small files instead of several large data streams.
I recently had that experience when we had to restore several hundered
gigabytes. the home directories of users were 4 times slower thamn the backup
partition which hold backups of our machines bihind the firewall. those files
tend to be a few very large files of 2 Gb or more.
So lots of factors are involved and anyway writing to disk (specially raid 5)
is in general much slower than reading so backup times say nothing about
restore times. (my rule of thumbe is 4 times slower)
