BackupPC compares files in the pool using the checksum to find if the exact same file is in the pool or not. This is not a feature of rsync. Rsync has checksum checking too, where it is checking for if the file should be backed up or not and apply it to all files if --ignore-times option is used. I was first wrong and I thought this was done by BackupPC. Anyhow there is nothing to argue about. You are right, the thing I am talking about is not from backuppc. I could remove the --ignore-times option for better performance perhaps. > 2.) Tar full backups do *not* miss files. Thats true, I forgot about it but you still might have wrong incremental backups. > And with that, my troll-sitting quota is used up. See you. Sorry, and thanks.
