that's almost true. 1. rsync will copy over *everything* on the first backup (actually upto the first *full* backup), which might not be expected. In your case (you were doing tar backups anyway), that will not be a problem, but in cases where the switch to rsync is done because of bandwidth limitations, it should be noted. Actually, it also matters in your case, because if you only run one rsync incremental after switching, you'll probably observe that it is much slower than a tar incremental was before, so you should know why that is :). 2. You should do a full backup after switching transfer methods. There are subtle differences (see above), and a full backup will make sure everything is as the new transfer method expects. 3. I believe I recall reading that *restoring* a backup *made with rsync* with the tar XferMethod produces warnings (or errors?) - probably because tar doesn't understand the "deleted file" entries in the attrib files. While I can't see that giving incorrect results, it probably won't give you a good feeling to read that your restore completed with 579 errors, which you'll have to individually check. So if you need to restore an old backup after having switched the XferMethod, it would probably be a good idea to switch it back for the restore. Recent versions of BackupPC (>= 3.0.0, I believe) record the XferMethod a backup was done with in the backups file (but I don't think they automatically use that information for doing a restore). Aside from that, though I also like to point at the Wiki, I believe it is still sort of non-functional. At least I can't find anything except the main page ...
