A free pack of simple scripts for incremental backups to untrusted host arnie is a tremendously simple system for performing incremental backups to remote untrusted hosts, with support for encrypted files on the remote host. While the scripts are simple and recent, they are also robust and are in active use on the author's own servers, and there are provided together with a comprehensive suite of tests to prove it.WARNINGS: · The arnie tools do not incrementally archive changes in user/group ids nor access, modification or creation times (however, they could very easily be modified to do so and I might do that at some point). They do, however, track permission changes, and obviously added files, deleted files, and file content changes (the file comparison is carried out using a simple MD5 sum).· Also note that the incremental archives produced by these programs are not of optimally minimal size, i.e. we do not store diffs, but rather we store entire files when they change, and we do not track file location moves. Therefore this might not be a suitable solution if you have a large binary file from which only a few blocks are changing between backups (the entire file will be backed up every time). Our solution is meant to work well on directories with many small to intermediate size files (such as a CVS source code repository). Requirements: · Python 2.4 or later What's New in This Release: · Automatically compress archives in gzip or bzip2 format; · Automatically encrypt archives using a GnuPG key (specify the key Id or name); · Automatically send the archive file to a remote host using scp. This is just a convenience: alternatively you can capture the name of the archive and send it any way you like (ftp, other...); · Tracks and restores permissions changes on directories and files; · Works with empty directories; · Works with symbolic links; · An alternate location for the history file can be specified; · Regexp patterns for excluding files in the backup can be provided; · You can restore at any of the times the backups were made (the restore script has an option); · The archives are simply stored as GNU tar files, so you can open them manually if so desired.
