Package: backuppc
Version: 4.4.0-6+b1
Severity: important
Dear Maintainer,
after a recent update (probably to a Perl library), a bug in BackupPC leads to
it destroying
its configuration files when saved from the BackupPC admin console.
On a system updated to the current versions of Debian Testing, I made minor
modifications to
the configuration setup in the web admin console and pressed the "Save" button.
After that, any access to the admin console led to an internal error message.
Restarting the
backuppc service fails from that point on as well.
Reason is that any configuration file saved this way is destroyed, as the
brackets, [] and {},
required to store arrays or maps respectively, are replaced by ordinary
brackets ().
CAUTION: For certain configuration files, this problem will *not* lead to
backups reporting failure, but generating
faulty or incomplete backups due to misinterpretation of the config files,
along with lack
of proper validation of the config files.
This bug is reported upstream: https://github.com/backuppc/backuppc/issues/466
A fix seems to be available and extremely easy to apply (not verified myself),
but is not
yet part of an upstream release.
