Unless there is a truly pathological number of small files (think tens if not hundreds of millions), I don't think you can explain a 21 hour backup period. My Raspberry PI 4 on a home network backs up my Ubuntu 18.04 with 2.7GB and 321K files in under 12 minutes. And I think that is with several simultaneous backups. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
