Re: [BackupPC-users] Enhancements in rsync 3.0

The configurations options are a bit misleading. Rsync's implementation in BackupPC is pretty complicated. BackupPC uses the rsync binary to initiate the transfer, but then uses File::RsyncP to handle the actual file transferring.

File::RsyncP is a full implementation of the rsync protocol from front to back, so it needs to support the most recent version as well.

I think, youcan do that yourself, can't you?

1) Update your server to rsync 3.01
2) Update your clients to rsync 3.01
3) Use the appropriate options in the transfer-configuration of backuppc.

Hendrik
