[knot-dns-users] Missing private keys in backup

Hi (again), I was trying to backup and restore a server with the new knotc zone-backup/restore command. I recognized that only half of the private keys were in the backup, which leads to an error: 2020-12-08T14:44:00+0100 error: [xxx.] DNSSEC, failed to load private keys (not exists) 2020-12-08T14:44:00+0100 error: [xxx.] DNSSEC, failed to load keys (not exists) Shouldn't the backup contain all private keys? Thanks, Thomas
