INSTALLATION (from .tar.gz archive)

Debian Linux: Type 'debuild' to get a binary archive. Others: Run './install-sh' or 'sh install-sh' and follow the instructions.


Version 1.4

With some help from Joe Auricchio <>, backup2l should now run under Mac OS X 10.3 (but may still be unstable!). The following known restrictions apply:
- installing the GNU findutils, e. g. from fink (, in particular the GNU versions of 'find' and 'xargs'. - If no GNU version of sed is installed, the FILTER_* commands in the beginning of "backup2l" have to be changed to use per for filtering (just uncomment the respective lines there). - In some cases, the printf "%s" command of 'find' always returns 0 instead of the file size. This leads to incorrect size reports. - The date in the summary output is broken unless GNU date is installed. - [to be continued...]

Version 1.1

An new open driver architecture allows to use virtually any archiving program as a backend. Built-in drivers support .tar.gz, .tar.bz2, or .afioz files. Further user-defined drivers can be added as described in the sample configuration file 'first-time.conf'.

Due to major code changes, this release may be unstable. The latest stable release is 1.01. Archives created by the default driver ("DRIVER_TAR_GZ") are fully compatible with backup2l 1.01.

Version 0.9 & 0.91

Some versions of find (e. g. 4.1.7.) seem to have a bug so that printf does not produce leading 0's if requested. As a result, the .list.gz, .new.gz and .obsolete.gz files may contain entries like

4 11/11/01 02:07:17 0. 0 0777 /var/squid/some_file

instead of

4 11/11/01 02:07:17 0000.0000 0777 /var/squid/some_file

In backup2l 0.91, a workaround is implemented to guarantee the correct (2nd) format. Two issues have to be considered:

  1. Without leading 0's, a restore operation may fail.
  2. Backups are always created correctly. However, when switching to 0.91, differential backups may be larger than necessary.

It is recommended either to modify incorrect .list.gz, .new.gz and .obsolete.gz files manually or to purge the respective archives.
