  • Basic Bacula - Bacula 1 Training

*This s the continuation of the course Bacula 1: Open Source Backup Software, available at Udemy"

Using bpipe is the fastest, easiest, most automated and economic way of doing hot backups of specific application such Postgresql, Mysql, Firebird, Oracle databases; Xen and Kvm Virtual Machines export / snapshots; tar packages with several files; and more!

The bpipe plugins automatically creates, writes and reads from a FIFO, and is able to restore information directly to your application. E.g.: restore a database directly from Bacula, without the need to do any further operation. And you can do that with Bacula Community or Enterprise.

Any information that I send though the echo it goes but is not really stored on the FIFO; it is read directly by the Bacula and written into backup volume. You don't use disk space for that.

Training example applications:

  • MySQL
  • PostgreSQL
  • Firebird
  • LDAP
  • XenServer
  • Tar
  • Echo
  • etc.
Who is the target audience?
  • Bacula Users
  • DevOps
  • IT Managers

bpipe examples
7 Lectures 23:29

Plugin = "bpipe:/mnt/fifo/test.txt:/bin/echo fifo_teste:/usr/bin/tee /tmp/test.txt"

A simple echo FIFO backup

Plugin = "bpipe:/mnt/fifo/test.tar:/bin/tar -cf - /etc:/bin/tar -C /tmp -xvf -"

tar files

Plugin = "bpipe:/mnt/fifo/heitorfaria.sql:mysqldump -u root -p123456 --databases heitorfaria:mysql -u root -p123456"

# Plugin = "bpipe:/mnt/fifo/heitorfaria2.sql:mysqldump -u root -p123456 --databases heitorfaria:dd of=/tmp/heitorfaria2.sql" 

MySQL databases

Plugin = "bpipe:/mnt/fifo/heitorpg.sql:sudo -u postgres pg_dump --format=c heitorpg:sudo -u postgres pg_restore -d template1 -C"

# Plugin = "bpipe:/mnt/fifo/heitorpg2.sql:sudo -u postgres pg_dump heitorpg:tee /tmp/heitorpg2.sql"

PostgreSQL databases

Plugin = "bpipe:/mnt/fifo/heitorpg.sql:gbak -backup heitorfire stdout:gbak -replace stdin heitorfire_2"

Firebird Databases

Plugin = "bpipe:/mnt/fifo/ldap.ldif:slapcat -l /dev/stdout:/usr/sbin/slapadd -l /dev/stdin"

# Plugin = "bpipe:/mnt/fifo/ldap.ldif:slapcat -l /dev/stdout:dd of=/tmp/ldap_restore.ldif"

REMARK: always stop the LDAP daemon before restoring with the slapadd command.

Another example, specifying domain and configuration file for dump:

Plugin = "bpipe:/tmp/ldap_bkp.ldif:slapcat -f /etc/ldap/slapd.conf -b "dc=ifnmg,dc=edu,dc=br" -l /dev/stdout:tee /tmp/ldap_restore.ldif"

LDAP Bases

  • Safer method - restore to file:

Plugin = "bpipe:/tmp/vm_name.xva:snapshot=`xe vm-snapshot uuid=vm_uuid new-name-label=vm_name_snps` && xe template-param-set is-a-template=false uuid=$snapshot && xe vm-export vm=$snapshot filename=:dd of=/mnt/vm_name.xva"

  • Restore to Xen Server automatically - import:

Plugin = "bpipe:/tmp/vm_name.xva:snapshot=`xe vm-snapshot uuid=vm_uuid new-name-label=vm_name_snps` && xe template-param-set is-a-template=false uuid=$snapshot && xe vm-export vm=$snapshot filename=:xe vm-import filename=/dev/stdin sr-uuid=xen_storage_uuid"

Remark 1.: in order to fetch storage uuid use, in shell: xe pbd-list

It's advisible to remove generated snapshots during backups.

e.g.: xe vm-uninstall force=true vm=nome_vm_snps

  • ClientRunAfterJob script sample to delete all Xen snapshots since Bacula Job already backuped the VMs:

for i in `xe snapshot-list --minimal | sed -e 's/,/\ /g'` ; do xe snapshot-uninstall force=true uuid=$i ; done

  • A script to dinamically configure Bacula to backup all Xen host running VM:
