KVM LVM (Block Device) Incremental Backup
- This script is designed to do Live LVM Snapshot backups of KVM virtual servers
- Once it has created the LVM snapshot it will dd the LVM image & gzip it at the same time to a specified location.
- Once the gzip process is complete it will remove the LVM snapshot.
- This script requires the "bdb.cfg" file to exist which must contain the Virsh domain name and either yes or no for compression
- This script will do a once off full backup, and then do imcremental backups after that which are merged with the full backup.
- Please note on the remote side the LVM must not be active/mounted
