Hello, I just set up a BackupPC server with more than 100 clients. Most of them are backupped using rsync and ssh. The size of each client is 1-250GB. It took nearly two weeks to finish the initial full backup for all these clients. This was expected due to limited network bandwidth.
The default for clients is to keep one weekly full backup and six/seven daily incemental backups. Now BackupPC has a full backup of all clients. Unfortunately it starts with full backups again as the first ones are older than seven days. But I really wonder about the time, BackupPC takes for doing the second round of full backups. I tought that only changed files were transfered when using rsync. And the stats look like I'm right. But still, full backups take up to two days, even if only a few new files are transmitted. Given that BackupPC still does a lot of parallel backups, maybe reading the list of files with rsync takes that long, even if I don't believe it. I restarted BackupPC and that way stopped all active full backups. After that I started incremental backups for several hosts. And now I was really surprised: the incremental backups are much faster than the full backups. Even for hosts with 150GB of data, the incremental backup (few new files) took just some hours, while the second full backup for the same host took days. Did I get anything wrong? I'm curious to hear your opinions.
