Re: [BackupPC-users] Enhancements in rsync 3.0

[Paul M. <pc...@gm...>]

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.
