# Rsync time backup
Time Machine style backup with rsync. Should work on Linux, Mac OS X and Windows with Cygwin.
# Installation
git clone https://github.com/laurent22/rsync-time-backup
# Usage
rsync_tmbackup.sh <source> <destination> [excluded-pattern-path]
## Examples
* Backup the home folder to backup_drive
rsync_tmbackup.sh /home /mnt/backup_drive
* Backup with exclusion list:
rsync_tmbackup.sh /home /mnt/backup_drive excluded_patterns.txt
## Exclude file
An optional exclude file can be provided as a third parameter. It should be compabible with the `--exclude-from` parameter of rsync. See [this tutorial] (https://sites.google.com/site/rsync2u/home/rsync-tutorial/the-exclude-from-option) for more information.
# Features
* Each backup is on its own folder named after the current timestamp. Files can be copied and restored directly, without any intermediate tool.
* Files that haven't changed from one backup to the next are hard-linked to the previous backup so take very little extra space.
* Safety check - the backup will only happen if the destination has explicitely been marked as a backup destination.
* Resume feature - if a backup has failed or was interrupted, the tool will resume from there on the next backup.
* Exclude file - support for pattern-based exclusion via the `--exclude-from` rsync parameter.
* "latest" symlink that points to the latest successful backup.
* The application is just one bash script that can be easily edited.
# TODO
* Manage the backups in a way similar to Time Machine - hourly backups for the past 24 hours; daily backups for the past month; weekly backups for the previous months.
* Other minor changes (see TODO comments in the source).
