Gerrit server backup

Goal: create a cronjob that sends a tar backup of Gerrit.

On linode01.ovirt.org

Create Gerrit backup user, saving the password in /root/passwords: useradd gerrit-backup passwd gerrit-backup Create SSH key structure: touch /home/gerrit-backup/.ssh/authorized_keys vi /home/gerrit-backup/.ssh/authorized_keys # add id_rsa.pub contents chmod 644 /home/gerrit-backup/.ssh/authorized_keys chmod 700 /home/gerrit-backup/.ssh/ Create backup directory and sub-dir tree: mkdir -p /home/gerrit-backup/backup/src

On gerrit.ovirt.org

Backup git source directories

Switch to the Gerrit user: su - gerrit2 Create an SSH key without a passphrase, then copy the public key for the authorized_keys file on the remote host: ssh-keygen # set no passphrase cat .ssh/id_rsa.pub Prepare backup script: mkdir /home/gerrit2/bin vi bin/gerrit-backup.sh Bash script to remotely backup git repository directories using rsync over ssh: #!/bin/bash # # Gerrit backup script - git source backup # # 0.1 Alpha - 20111207 Karsten Wade <kwade@redhat.com> <quaid@iquaid.org> # # Copyright 2011 Karsten Wade <kwade@redhat.com> <quaid@iquaid.org> # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. # # Set variables RSYNC="/usr/bin/rsync" RSYNCOPTS="-az -e" SSH="/usr/bin/ssh" GITSRC="/usr/local/src/git/" REMOTEUSER="gerrit-backup" REMOTEHOST="ovirt.org" REMOTEDIR="gerrit.ovirt.org-src-backup/src/" # Run backup - rsync local git source to remote backup directory # Note: gerrit user has sshkeys with no passphrase $RSYNC $RSYNCOPTS $SSH $GITSRC $REMOTEUSER@$REMOTEHOST:$REMOTEDIR Make script executable: chmod 700 bin/gerrit-backup.sh Make cronjob run every day at 2200 EST crontab -e Contents of user's crontab: # mail all output to root MAILTO=root # Run at 2200 (10 pm) system time every day 0 22 * * * $HOME/bin/gerrit-backup.sh # Run database backup at 2220 (10:20 pm) system time every day 20 22 * * * $HOME/bin/gerrit-database-backup.sh # Run backup of /home/gerrit2 at 2240 (10:30 pm) system time every day 40 22 * * * $HOME/bin/gerrit-gerrit2-home-backup.sh
