Returning to this after a while, I answer to myself about how I solved this,
and it remains as a reference for those who have been presented with the same
concern.
The problem is how to handle this when you have multiple catalogs. Since you
can not define a single Scratch pool for multiple catalogs (if you do not
specify which catalog to use in the Scratch Pool definition, Bareos assigns one
automatically). What I did was define a Scratch Pool for each catalog, and
indicate explicitly, for each pool defined, which Scratch Pool should use.
For example; Assume that I have three catalogs defined: Catalog-A, Catalog-B
and Catalog-C, as follows:
============================================
"/etc/bareos/bareos-dir.d/catalog/Catalog-A"
============================================
Catalog {
Name = "Catalog-A"
Description = "First catalog: Catalog A"
DB Driver = postgresql
DB Name = bareos_Catalog-A
DB User = bareos
# echo bareospassword | sha224sum
DB Password = 1a58321bf4ec7a4da07e6e87d3b011149a61b9d7b6bf7d2434769bf1
}
============================================
"/etc/bareos/bareos-dir.d/catalog/Catalog-B"
============================================
Catalog {
Name = "Catalog-B"
Description = "Second catalog: Catalog B"
DB Driver = postgresql
DB Name = bareos_Catalog-B
DB User = bareos
# echo bareospassword | sha224sum
DB Password = 1a58321bf4ec7a4da07e6e87d3b011149a61b9d7b6bf7d2434769bf1
}
============================================
"/etc/bareos/bareos-dir.d/catalog/Catalog-C"
============================================
Catalog {
Name = "Catalog-C"
Description = "Third catalog: Catalog C"
DB Driver = postgresql
DB Name = bareos_Catalog-C
DB User = bareos
# echo bareospassword | sha224sum
DB Password = 1a58321bf4ec7a4da07e6e87d3b011149a61b9d7b6bf7d2434769bf1
}
Then, first define the Scratch Pool for each catalog, as follows:
==========================================================
"/etc/bareos/bareos-dir.d/pool/Scratch for Catalog-A.conf"
==========================================================
Pool {
Name = "Scratch for Catalog-A"
Catalog = Catalog-A
Pool Type = Scratch
# I am using IBM cleaning cartridges, which come
# with the barcode printed with the prefix CL
Cleaning Prefix = CL
}
==========================================================
"/etc/bareos/bareos-dir.d/pool/Scratch for Catalog-B.conf"
==========================================================
Pool {
Name = "Scratch for Catalog-B"
Catalog = Catalog-B
Pool Type = Scratch
# I am using IBM cleaning cartridges, which come
# with the barcode printed with the prefix CL
Cleaning Prefix = CL
}
==========================================================
"/etc/bareos/bareos-dir.d/pool/Scratch for Catalog-C.conf"
==========================================================
Pool {
Name = "Scratch for Catalog-C"
Catalog = Catalog-C
Pool Type = Scratch
# I am using IBM cleaning cartridges, which come
# with the barcode printed with the prefix CL
Cleaning Prefix = CL
}
So now, with the Scratch Pools already defined, it only remains to specify what
the Scratch Pool will be for each pool, as follows:
===========================================================
"/etc/bareos/bareos-dir.d/pool/Some pool of Catalog-A.conf"
===========================================================
Pool {
Name = "Some pool of Catalog-A"
Description = "A pool of tapes, using Catalog-A"
Catalog = Catalog-A
Pool Type = Backup
Storage = Tape
Cleaning Prefix = CL
Maximum Block Size = 524288
Catalog Files = yes
Recycle = yes
Scratch Pool = "Scratch for Catalog-A"
Recycle Pool = "Scratch for Catalog-A"
Volume Use Duration = 1 week
Volume Retention = 1 week
Job Retention = 1 week
File Retention = 1 week
}
==============================================================
"/etc/bareos/bareos-dir.d/pool/File pool using Catalog-B.conf"
==============================================================
Pool {
Name = "File pool using Catalog-B"
Description = "A pool of backups on files, using Catalog-B"
Catalog = Catalog-B
Pool Type = Backup
Storage = File
Catalog Files = yes
Volume Use Duration = 1 week 3 days
Volume Retention = 1 week 3 days
Job Retention = 1 week 3 days
File Retention = 1 week 3 days
Recycle = yes
Scratch Pool = "Scratch for Catalog-B"
Recycle Pool = "Scratch for Catalog-B"
}
====================================================================
"/etc/bareos/bareos-dir.d/pool/WORM-Like Tapes using Catalog-C.conf"
====================================================================
Pool {
Name = "WORM-Like Tapes using Catalog-C"
Description = "Unique tape backups, forever, using Catalog-C"
Catalog = Catalog-C
Pool Type = Backup
Storage = Tape
Cleaning Prefix = CL
Maximum Block Size = 524288
Catalog Files = yes
Volume Use Duration = 100 years
Volume Retention = 100 years
Job Retention = 100 years
File Retention = 100 years
Maximum Volume Jobs = 1
# Here, the first thing that one would think about,
# is that it does not make much sense to have a Scratch Pool
# for a backup that will last 100 years, however, it
# is convenient to send the newly pre-labeled tapes to the
# Scratch Pool, so that when a job that will use this pool,
# Bareos has where to look for the new tapes.
Scratch Pool = "Scratch for Catalog-C"
#Recycle = yes
#Recycle Pool = "Scratch for Catalog-C"
}
Now, for the tapes, from bconsole, you can label a series of tapes by sending
them to the corresponding Scratch Pool for each catalog; for example:
root@bareos-test:~# bconsole
Connecting to Director localhost:9101
1000 OK: bareos-dir Version: 18.2.4rc1 (25 Sep 2018)
Secure connection with cipher ECDHE-PSK-CHACHA20-POLY1305
Enter a period to cancel a command.
*label storage=Tape pool="Scratch of Catalog-A" slots=1-6 barcodes
*label storage=Tape pool="Scratch of Catalog-C" slots=7-10,21 barcodes
*q
With this I managed to solve my problem. Bareos searches for tapes in the
Scratch Pool, and since a Scratch Pool was defined for each catalog, and it was
made explicit for each pool of each catalog, which Scratch Pool corresponded,
the problem was solved.
Regards!
