Following on from my post about excluding the base OS with a Bacula FileSet, I decided to exclude some more.

The starting point

Here are the baselines:

*estimate level=full job="knew jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client knew-fd at knew.int.unixathome.org:9102
2000 OK estimate files=496,579 bytes=70,810,186,782

*estimate level=full job="tallboy jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client tallboy-fd at tallboy.vpn.unixathome.org:9102
2000 OK estimate files=163,040 bytes=3,628,862,728

*estimate level=full job="zuul jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client zuul-fd at zuul.unixathome.org:9102
2000 OK estimate files=574,237 bytes=117,950,136,800

What else will I exclude?

I decided to exclude the following as well:

/tmp
/usr/local/man
/usr/local/share/licenses
/usr/local/share/locale
/var/cache/pkg
/var/db/ports
/var/db/portsnap
/var/tmp/nginx

Adding iocage support

Along the way, I extended the Exclude to work on server using the iocage jail management tool. I also split the Exclude out into its own file.

Here is the iocage Exclude:

    Options {
      Exclude = yes
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/basejail"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/bin"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/boot"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/lib"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/libexec"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/rescue"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/sbin"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/sys"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/bin"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/include"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/lib"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/libdata"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/libexec"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/ports"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/sbin"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/share"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/src"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/var/ports"

      # mounts
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/dev"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/proc"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/basejail"

      # other
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/tmp"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/local/man"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/local/share/licenses"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/usr/local/share/locale"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/var/cache/pkg"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/var/db/ports"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/var/db/portsnap"
      WildDir = "/iocage/jails/*/root/.zfs/snapshot/snap4back/var/tmp/nginx"
    }

The ezjail version

And the ezjail version:

    Options {
      Exclude = yes
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/basejail"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/bin"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/boot"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/lib"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/libexec"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/rescue"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/sbin"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/sys"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/bin"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/include"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/lib"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/libdata"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/libexec"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/ports"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/sbin"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/share"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/src"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/var/ports"

      # mounts
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/dev"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/proc"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/basejail"

      # other
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/tmp"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/local/man"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/local/share/licenses"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/usr/local/share/locale"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/var/cache/pkg"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/var/db/ports"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/var/db/portsnap"
      WildDir = "/usr/jails/*/.zfs/snapshot/snapshot-for-backup/var/tmp/nginx"
    }

The results

The files are using like this:

FileSet {
  Name = "zuul jail snapshots"
  Include {
    Options {
      signature = MD5 
    }

    Exclude Dir Containing = .NOBACKUP

    File = "\\|/usr/home/dan/bin/jail-snapshots-for-backup.sh list"

    @/usr/local/etc/bacula/fileset-excludes-for-jail-snapshots-ezjail.conf
  }
}

After making these changes, here are the results:

*estimate level=full job="tallboy jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client tallboy-fd at tallboy.vpn.unixathome.org:9102
2000 OK estimate files=72,844 bytes=1,950,880,305
*

*estimate level=full job="knew jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client knew-fd at knew.int.unixathome.org:9102
2000 OK estimate files=416,890 bytes=63,792,808,999
*

estimate level=full job="zuul jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client zuul-fd at zuul.unixathome.org:9102
2000 OK estimate files=468,439 bytes=113,252,932,377

A final tweak

I thought I could do some more, so I went into knew and added some more .NOBACKUP files, getting it down to:

*estimate level=full job="knew jail snapshots"
Using Catalog "MyCatalog"
Connecting to Client knew-fd at knew.int.unixathome.org:9102
2000 OK estimate files=388,137 bytes=62,326,817,901

It was zi who suggested I use WildDir. I don’t recall what solution I was thinking of before, but it wasn’t as good as this.
