Hi,
I'm with Debian/Squeez and Bacula 5.0.2.
I use the tape library TS3100 with a IBM 3573-TL.
Questions:
1) mount a tape to the drive 2
2) speed up the backup with LTO5
1)
And i've got 2 drives.
A drive 1 is mounted with a tape e.g. LT00X.
And i'd like to use the drive 2. So i've mounted it with a tape : LT00Y.
Then, the drive 2 is loaded with the tape - LT00Y-, but it is said that
drive is mounted with the tape LT00X !

Device "Drive-1" (/dev/nst0) is mounted with:

The drive 2 should have mounted with LT00Y but not LT00X !
Could someone explain me about this behaviour, please ?
Here's my bacula-sd.conf
Autochanger {

> Drive-2

2) The speed of my backup is not very fast:
Rate: 43362.5 KB/s
I'd like to have some feedback about the LTO5 and the speed that could be
reached...
In my bacula-dir, i do not use the "Spool data" option.
Thank you in advance for your help.
Peace !
