I'm making a small backup server for my office. It's proven to be difficult because while the documentation is great on BackupPC, it's not helpful. I've installed rsyncd on my clients' computers and most of the time they work fine. However, when it gets to certain files (one client wants their email files backed up), rsyncd doesn't have permission to go there:

Starting file 1 (Internet Calendar Subscriptions.pst), blkCnt=0, blkSize=2048, remainder=0
Internet Calendar Subscriptions.pst: size doesn't match (2049024 vs 0)
Internet Calendar Subscriptions.pst got digests 6a39da2a50a4ca618e159d8c449fe824 vs 6939da2a50a4ca618e159d8c449fe824
Internet Calendar Subscriptions.pst: fatal error: md4 doesn't match on retry; file removed
MD4 does't agree: fatal error on #1 (Internet Calendar Subscriptions.pst)
Remote[1]: rsync: read errors mapping "pData/Local/Microsoft/Outlook/Internet Calendar Subscriptions.pst" (in OUTLOOK): Permission denied (13)
Starting file 3...
... Does this another couple of times with other files
Got exit from child
Done: 6 files, 5835299 bytes
incr backup started back to 2013-06-29 19:33:10 (backup #0) for directory Zfiles
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Error connecting to rsync daemon at client-lt:873: unexpected response 

Got fatal error during xfer (unexpected response 
Backup aborted (unexpected response 

Is the problem with the Client? I think it is, but how do I fix it?

Do I have to find the username rsyncd runs in and give it read permissions to the folder it's failing in? If so, how do I do it?

I'm getting really frustrated with this system. It seems to be exactly what I want, but the errors are poorly documented and I'm about to scream.

Any help would be amazing as I would really like to get this to work.
