Item n: Multiple concurrent jobs from one fileset and job definition
Date: 25 November 2005

Status:
What: I want to start multiple backup jobs on one client to get the
fastest possible backup of my server but I do not want a
complicated configuration or restore process.
The director could parse the FileSet and start one job for
each File entry and send a modified FileSet definition to the
file daemon for each job.
A confiuration option should be used to enable or disable this
feature and MaximumConcurrentJobs should be used to limit the
number of jobs running at the same time.
Bacula must be modified to handle full backups with the same
ClientId, PoolId, FileSetId and SchedTime as one full backup
and include all of them when making a restore or verify.
No modifications has to be done to file and storage daemons.
This is a example FileSet in bacula-dir.conf:
FileSet {
Name = "Full Set"
Include {
Options {
onefs=no
Start_One_Job_For_Each_File_Entry = Yes
}
File = /
File = /usr
File = /home
File = /home/biguser
}
Exclude { }
}
This is the FileSet configurations sent to the file daemon for
this example:
Job 1: Include /, Exclude /usr, /home
Job 2: Include /usr
Job 3: Include /home, Exclude /home/biguser
Job 4: Include /home/biguser
Why: Multiple concurrent backups of a large fileserver with many
disks and controllers will be much faster.
Notes: I am willing to try to implement this but I will probably
need some help and advice.
