Databases generally back up much faster than file systems because they're,
well, databases. They can stream data faster and you're also backing up one
or two files instead of thousands to millions.
They often compress much better as well and you see improvement in the
transfer rate because with one drive your tape drive is the limiting factor.
By compressing the data you get more data on to the tape in the same amount
of time (i.e. if you're using DLT, with 5MB/sec native write speed, and you
can compress 1.5:1, you're actually writing 7.5MB/sec).
Backup Exec does work fine for backing up CIFS filers, but it all depends on
how much data you have to back up. If you're backing up a couple hundred
GB, it'll probably work. More than that, you probably want a more scalable
solution (e.g., multiple tape drives spinning during a backup over GbE, or
local attach NDMP backups).

Not true. I am using Backup Exec (8.0) to backup my Filer and it works
fine. Installing an agent on an NT server would allow the backup to go
significantly faster, however. Backing up over 100 Mbps LAN:
Backup of Filer: 189 MB/minute
Backup of Exchange server w/ agent: 332.7 MB/minute (local disks)
Backup of SQL server w/ agent: 311.2 MB/minute (local disks)
