Simple yet Powerfull for incremental backup.
Required packages,
Rsync
rsnapshot
You can do it for remote servers also.
I have configure it for local files only.
#yum install rsnapshot rsync -y
created backup_root /backup/
mkdir /backup/
Off course it has to be on diffrent hard disk as we are taking backup.
But I created on local disk for testing.
#vim /etc/rsnapshot.conf
Set snapshots root directory:
snapshot_root /disk1/backup/Configure backup policy
interval hourly 6 # run 6 times a day means every 4 hour
interval daily 7 # and everyday and keep for 7 days.
#interval weekly 4
#interval monthly 3
I set it for hourly and weekly only.
Specify local and remote backup directories
Find out comments that read as follows:
############################### ### BACKUP POINTS / SCRIPTS ### ###############################
backup /etc/ localhost/
#backup /usr/local/ localhost/
backup /var/log/ localhost/
Save and close the file.
