dctr's rdiff-backup script

This script started as my personal backup script, but as it is getting more general and versatile, i decided to put it on github.

Installation

1. Put /bin and /etc on your disk

---

• /usr/local/bin and /usr/local/etc, or
• ~/.local/bin and ~/.local/etc

Note: At the moment, etc has to be in the same folder as bin, as files are included via ../etc/...,

2. Adapt drdbs.conf

---

drdbs.conf is well documented. Adjust it to your needs.

3. Adapt drdbs.exclude

---

This is the most important part: Select, what you want to include or exclude in your backup.

1. drdbs.exclude uses rdiff-backup's globbing syntax (basic part explained below)
2. The script includes / to provide complete relative paths
3. To human logic, the file is interpreted in reverse order

Syntax

• Lines starting with - mean "exclude".
• Lines starting with + mean "include"
• * matches anything but "/" (folder separator), therefore * means "ONE folder (or file)"
• ** matches "/" too, so **/foo means "any file foo in any folder of any nesting depth"

Creating your own config

As the backup starts at / and you usually only want to backup selected folders (but not e.g. /dev), building you own exclude should start with the following line.

- **

As the file is interpreted in reverse order, any further includes have to be made above that line.

+ /home
- **

You can place an exlude above an include to make an exception for this include

- /home/eve
+ /home
- **

This would backup all home folders, but not Eve's .

You can find an example drdbs.exclude in the etc directory of this repository.
