Backup Checker is a command line software developed in Python 3.4, allowing users to verify the integrity of archives (tar,gz,bz2,lzma,zip,tree of files) and the state of the files inside an archive in order to find corruptions or intentional of accidental changes of states or removal of files inside an archive.

The major feature of this new version is the ability of Backup Checker to use Unix streams. Using classic Unix tools like OpenSSH or wget, Backup Check is able to verify a remote tar.{gz,bz2,xz} archive. The following example verifies a tar.gz archive located on remote server through SSH:

$ ssh -q server "cat /tmp/backup.tar.gz" | ./backupchecker.py -c . -

Another short example with the FTP protocol, to verify a tar.bz2 archive located on a remote server through FTP:

$ wget --quiet -O - ftp://user:pass@server/backup.tar.gz | ./backupchecker.py -c . -

Moreover in this release, a new option –configuration-name allows the user to define a custome name for the files generated by Backup Checker (default is defined from the name of the archive using the -g or -G options).

It is a major step for Backup Checker. It is indeed easier and easier to use Backup Checker in your own scripts, allowing to fully automate your backup controls.

Several companies now use Backup Checker to secure their backups. Let us know if we can help you.
