rbme | RSYNC BACKUP MADE EASY | Continuous Backup library

rbme is a Shell library typically used in Backup Recovery, Continuous Backup applications. rbme has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Using rsync for backups is becoming more and more popular on UNIX/Linux systems. Especially the variant with hardlinks on the backup media to conserve disk space has proven itself to be a very reliable backup solution. The method is already widely published on the Internet (e.g. this is a nice introduction), so that I will save myself the trouble of repeating it. In a nutshell you get perpetual incremental backups that appear as full backups (for each day) and thus allow easy restore or further copying to tape etc. After the initial full backup RBME will forever do incremental backups against the last backup to conserve time and network bandwidth. RBME is a simple tool to assist in implementing a general backup solution based on rsync and hardlinks with an automated management of the disk space on the backup media. This is achieved by removing old backups from the backup media in a way which will ensure that (over the long run) the amount of backups should even out for all hosts involved. This is also the major reason for me to write this script, I didn't find a suitable script (that would manage the backup space and also watch the inodes) when I needed it. The other reason is of course the fact that studying another script would take at least the same time as writing my own and in such cases I tend to write my own.
