Of course. It's all a matter of personal preference and personal needs.
There is one caveat though about full jobs and backup speed. It's all ok
if you're backing up just files and have no problem reading them with
the filedaemon. If you have some uncommon scenarios (like backing up
shares via CIFS from devices you can't install FD on or using plugins to
generate data for FD - in my case it might be a script reading package
list or a database dump), you might face SD starvation leading to
shoeshine. I suppose you could even hit uderruns with big flat
directories (but I'm not sure here - maybe the files would just be read
sequentially and not suffer that much from long directory listing).
It's always good to do an analysis of what you need and what you have :-)

Yup this is a personal decision, that's right and every sysadmin
should check their own needs and possibilities.
We have 6TB (15TB compression) LTO-7 cartridges and about 20 TB of data.
I decided to do it this way because I read in the originally bacula
book (from Philippe Storz) how backup is handling the tapes and
because even Philippe Storz himself advised me that this is a good way
to backup on single tapes.

Well, not everyone has long enough tapes to always do full backups
;-) After all the whole concept of Inc and Diff backups didn't come
from nothing.

Hi,
Another possibility is not to spool and not to backup incremental
nor differential jobs.
For restoring speed and for your tape health it is better to always
do full backups, especially if you have no autochanger.
I deleted all jobs which do no full backup.
I did the configuration in a way, that once a month it asks me to
change the tape and this for each job. In this way I do a full
backup twice in a year of each job by manipulating tapes only once
per month. This is for me an easy way to handle the tapes.
The job tells me to insert cartridge 1 and as soon it is inserted,
the job continues automatically. One month later it asks me for
cartgidge 2 and so on.
Let me know if you are interested to know how to configure such a
handling.

Birgit

Hi there,
this is my schedule set:
Schedule {
Name = "CR-WeeklyCycle"
Run = Level=Full 1st sun at 7:00
Run = Level=Differential 2nd-5th sun at 7:00
Run = Level=Incremental mon-sat at 7:00
}
The backup is stored on a LTO tape, changed manually - no autoloader.
Looking on the schedule, a tape of the increment pool is insert on
Saturday morining.
When now a differential or full backup is started, it checks first
if the right tape is insert.
So I have do by manpower, that the right tape is available before
the backup starts.
All backup jobs like inc, diff and full have spooling active.
Is there a way, that the nackups starts, and spools also if the
wring tape is insert and after changing to the right tape, the
despooling process starts or must I split it each backup in two
jobs: copy to hdd and then to tape?
Thanks for any useful hints, Frank
