Re: [Amanda-users] Amanda backup problem - a tape error occured

2008-12-22 Thread Jean-Louis Martineau
Are you sure of the size of your tape? 4Gb is with compression or not, 
Do your data are compressible or not, are you using software compression?

Right -- if you're doing 14 backups (2 weeks, every day), you're not
going to fit that on 12 tapes.  You need 15 tapes.




I wasn't clear enough. I run a backup every working day (monday to friday), 
which means 10 backup per cycle so I guess 12 tapes is enough.

Furthermore, it looks like you don't have enough holding-disk space:



FAILED [no more holding disk space]

  

which is causing your dumps to go straight to tape, which isn't very efficient.




I confess I haven't configurated this part. I understood (maybe I'm wrong) that 
it would work anyway.

Furthermore, your tape only wrote a bit over 1G:



DailySet-05   2:11  1140224K   28.8 1 0

  

which is 28% of the length you specified in your tapetype definition.
Is there a problem with the tape?  Or is the tapetype definition
incorrect?




I'm using 4Go tapes. They are all new and I have the same problem for every 
tape. I've used amtapetype for amanda.conf configuration.
Below is the extract from amanda.conf related to the tapetype definition.

  

define tapetype HP-C1537A{
length 3868 mbytes
filemark 225 kbytes
speed 491 kps
}

The tape got full after 1783648 was written, you need bigger tape.




The capacity of all my tapes is 4Go. I feel like Amanda doesn't overwrite the tape but 
just fill the tape until it's full and then exit with the previous error message : 
The tape got full after 1783648 was written, you need bigger tape.

PS:can anybody tell me why I can't see my original post but only the replies ?
