Version 3.3

Prior to this version, you could define a list of file suffixes (extensions) that would never be compressed. You could also set a minimal size of files so that files below that size would not be compressed. If you do not change anything about this in your configuration file, the behavior stays the same. However, now you can also define a list of file suffixes always to compress in addition to the prior options which let you define a list of file suffixes which should not be compressed, plus a minimal file size. For files not fitting in these categories will make an estimation if compression might reduce the file size. Naturally, you can also define your own rules with this functionality. See section ``How to define if a file should be compressed'' for detailed information.
Isolated mode:
If you are traveling, for example, with a laptop and have no connection to your backup, you now can store delta backups (relative to your ``big'' local backup) on a small media device (e.g., a memory stick) and integrate these backups later into your central one. See section ``isolated mode / offline backups'' for detailed information.
Replication of backups:
Allows you to set up the replication of your backup to other disks / locations. This can be used to make continuous copies of your backup. See section ``replication of backups'' for detailed information.
Allows you to copy / hard link backups to other ones. It is like running cp -a but hard linking all identical files to selectable directories. It can also be used to support the replication of backups in special situations. If you have small backups you want to copy onto another disk, this might be the right tool for you also. See section for detailed information.
This tool is intended to find files in the source that might have changed over the time without the user's interaction or knowledge, for example by bit rot. See section for detailed information.
