I have taken over maintenance of the BackupPC package and have made the update to 4.1.0 available through COPR[1] for now for a couple of reasons:

1. It's a huge change, hardlinks are no longer used for deduplication, but v4 can read v3 backups.

2. Some of the settings in /etc/BackupPC/config.pl were tweaked and need manual attention after the upgrade.

See https://backuppc.github.io/backuppc/BackupPC.html#BackupPC-4.0 for details.

The plan is to update f26 and rawhide to v4 and leave f25 and EPEL alone. Those that want to update to v4 can use the COPR.

Thanks,
Richard
