My version does what your patch posted a couple of days does only faster & probably better (i.e. your version may miss some cases where there are pool dups and unlinked pc files with multiple links). > Will your new version catch the "this has multiple hard links but > not into the pool" error I was seeing?

My version simple extends to also test pc files with more than one link and fix them as appropriate though I haven't test it. ------------------------------------------------------------------------------ _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
