Description of problem: BackupPC will neither backup nor restore (manual or web interface) config.pl -> $Conf{TarClientPath} = '/usr/bin/gtar'; config.pl -> $Conf{XferMethod} = "tar"; Version-Release number of selected component (if applicable): BackupPC-3.3.1-2.fc23.x86_64 How reproducible: Attempt backup full or incr from web interface. Monitor of log file shows a quick failure. Steps to Reproduce: 1. See above 2. 3. Actual results: Backup or restore via web interface (and likely manually as well) quickly fail. Expected results: BackupPC backs up and restores files (as in Fedora 22 and prior) Additional info: From BackupPC logs: 2015-09-01 22:03:11 User backuppc requested backup of rumble (rumble) Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE (\w+)}(\+?)/ at /usr/share/BackupPC/lib/BackupPC/Lib.pm line 1268.

Compilation failed in require at /usr/share/BackupPC/sbin/BackupPC_Admin.pl line 108. This is beyond my time and attention span at this time. I am happy with successful backups at this time. Would method rsync work? My guess is not, as Perl code is likely used by all methods.
I just ran into this bug this morning. Wondering where/what the root cause, i.e. a Perl package upgrade? A couple of backups ran yesterday, one rsync backup at 15:00, and localhost (gtar) at 18:00. No package changes for BackupPC (Version 3.3.1), no perl-* packages upgraded since 11/19.
It looks like Perl 5.22 deprecated 'defined(@array)' per: http://perldoc.perl.org/functions/defined.html I guess it's usage threw a warning before but it has since been hardened to an error. I found a few reports of other Perl based package(s) discussing this problem: https://github.com/kentcdodds/cloc/issues/1 http://sourceforge.net/p/cloc/bugs/135/ https://bugs.archlinux.org/task/45494 I think the fix for this might be only a few lines, working on patch now.
Created attachment 1104083 [details] Patch to strip out 'defined(@array)' type statements
The attached patch fixes the 'defined(@array)' error and I am once again able to browse backups on the web.(In reply to Dominique Brazziel from comment #2) > It looks like Perl 5.22 deprecated 'defined(@array)' per: > > http://perldoc.perl.org/functions/defined.html > > I guess it's usage threw a warning before but it has since been hardened to > an error.
