This repository contains a set of backup and snapshot scripts for oVirt virtual machines and Ceph volumes.
The main script is made to be called directly, the others are made just to be in turn called by the main scripts. Scripts are supposed to be run by a local user called "ovicbackup".
The script to be called directly is:
ovicbackup.sh
Be sure to install ovirt python components to use ovirt scripts, to correctly install and configure ceph client to use ceph scripts, to correctly install backy2 software as python module for the "ovicbackup" user, that runs the script.
Examples of script scheduling in crontab:
00 00 * * * /opt/ovicbackup/libexec/ovicbackup.sh ovicrbdsnapshot
30 00 * * 6 /opt/ovicbackup/libexec/ovicbackup.sh ovicrbdbackup
30 00 * * 7 /opt/ovicbackup/libexec/ovicbackup.sh ovicvmbackup
Secondary scripts are in turn called based on the argument passed to ovicbackup.sh, which is one of the three shown in the example crontab. Then operations are done on targets defined in lists:
/opt/ovicbackup/lists/ovicrbdsnapshot.list - list of ceph rbd volumes to be snapshotted
/opt/ovicbackup/lists/ovicrbdbackup.list - list of ceph rbd volumes to be cloned for backup
/opt/ovicbackup/lists/ovicvmbackup.list - list of ovirt/rhv vms to be cloned and exported for backup
There is also the script:
ovicbackupstatus.sh
It gives some output if it finds anomailes inside ".status" files; it gives no output if no anomalies are found: so it's useful for monitoring, suitable for monitoring tools.
Directory structure for these script on the machine that runs them, is as follows:
/opt/ovicbackup/libexec/ -> scripts
/opt/ovicbackup/lists/ -> list files
/opt/ovicbackup/etc/ -> config files
/opt/ovicbackup/log/ -> log files
/opt/ovicbackup/status/ -> status files
/opt/ovicbackup/tmp/ -> temporary files
