Re: [Bacula-users] Problems with De-Duplication
2015-08-22 20:03:58
To talk about deduplication in Bacula,
you must know that there are three types of deduplication:
1. File level dedup using Base jobs.
2. Block level SD dedup called "aligned block deduplication"
requiring a filesystems such as ZFS to do the dedup
3. Block level called "Global End Point" deduplication
Item 1 is has been available in the community version since the
beginning.
Item 2 is not yet available in the community, but after my
vacation, I hope to make a plugin that will be
compatible with the community version. If I can find the
time to concentrate on it, this could be
ready in January 2016.
Item 3 will probably not be offered to the community for another
3-4 years.
Best regards,
Kern

When will Bacula Enterprise deduplication be ported

Dear Heitor,
Could you check out my configuration?
I've configured De-duplication on a Bacula 7.0.5.9 - CentOS
7 ( client-fd is version 5.2 - Windows 8.1 Pro x64 ) with
the following properties:
A specific Pool for the base volumes:
Pool {
Name = BaseJobs
Pool Type = Backup
Label Format =
"${Level}-${Job}-${Day}-${Month}-${Year}-${Hour:p/2/0/r}${Minute:p/2/0/r}${Second:p/2/0/r}"
Use Volume _Once_ = yes
}
The specific FileSet for the base job:
FileSet {
Name = "BaseFileSet_Windows8.1"
Enable VSS = yes
Include {
Options {
signature = MD5
compression = GZIP
}
File = C:/Windows/
}
}
The base job:
Job {
Name = "BaseJob_Windows8.1"
Type = Backup
Level = Base
Client = tom-helpdesk-fd
FileSet = BaseFileSet_Windows8.1
Pool = BaseJobs
Storage = ns-bacula-sd
Messages = Standard
}
The JobDefs for the full backup job:
JobDefs {
Name = "Windows_Backup"
Type = Backup
Level = Full
FileSet = "Windows FileSet"
Messages = Standard
SpoolAttributes = yes
Priority = 10
Write Bootstrap = "/var/spool/bacula/%c.bsr"
Storage = ns-bacula-sd
}
The full backup job:
Job {
Name = "FrankPC-Backup"
JobDefs = "Windows_Backup"
Base = "BaseJob_Windows8.1"
Client = tom-helpdesk-fd
Schedule = "FrankPC_Backup"
Pool = RegularBackups
}
The client
Client {
Name = tom-helpdesk-fd
Address = 10.13.37.103
FDPort = 9102
Catalog = MyCatalog
Password = "~XXXXXXX" # password for
FileDaemon
File Retention = 60 days # 60 days
Job Retention = 6 months # six
months
AutoPrune = yes # Prune
expired Jobs/Files
}
