Re: [Bacula-users] question about bacula job speed

[ce]

for the bacula backups on the old bacula server ( for backups of a windows
client ), I never noticed that long bacula jobs for incremental and
differential ones.

on the new bacula server for the backups of one of the folder:

Elapsed timeLevelBytesFilesSpeed

13:45:29   Differential 2.17 MB 42 45.92 B/s 0.35

on the new bacula server for the backups of another folder on the same
client:
Elapsed timeLevelBytesFilesSpeed

03:00:03 Differential 932.23 MB 1.648 88.36 KB/s

how can I find out why there is such a difference? the second folder backup
has even more files for backup as you see above but it took less.
NOTE:

for the first folder: 22 G out of 500 G  free space
for the second folder 400 G out of 700 free space?
not sure if having more free space for the client folders, will affect the
speed of backup?

any help will be appreciated!

I don't understand how list media can show nothing at this point, unless you
did something to the catalog to remove them again.

Let's hope that doesn't happen again :-)

To remove everything:

Stop all bacula daemons and run the drop_bacula_database script to completely
delete the catalog.  Remove any labels from tapes by running

mt -f /dev/nst0 rewind
mt -f /dev/nst0 weof

for each tape.

Then recreate the bacula database and tables like you did initially.

The label command should do this.
