Hi There,

I am new to amanda. We are running Amanda version 2.4.1p1 on a Solaris 5.6 box. 
For one of my filesystem which around 82GB in size (22GB after compression) the 
amdump takes 15 hours to do a level 0 backup.... 



These dumps were to tape DAILY1-13.
Tonight's dumps should go onto 3 tapes: DAILY1-13, DAILY1-14, DAILY1-15.

Is this normal?  

We are using a DLT7000 drive to do this dump.
