My problem is still that rsyncP with rsyncd as client still retransmits
unchanged files. I reduced the testcase:
1) Full Backup. All files are transmitted, This is the logoutput from the
client:
2009/10/22 21:35:44 [3820] connect from UNKNOWN (192.168.5.9)
2009/10/22 21:35:55 [3820] rsync on . from baggub@unknown (192.168.5.9)
2009/10/22 21:35:56 [3820] send unknown [192.168.5.9] docsnsettings (baggub)
.musikproject/musikCube_u.ini 1913 <f???????
2009/10/22 21:35:57 [3820] send unknown [192.168.5.9] docsnsettings (baggub)
.musikproject/musik_collected_u.db 157696 <f???????
2009/10/22 21:39:32 [3820] send unknown [192.168.5.9] docsnsettings (baggub)
.musikproject/musik_u.db 28868608 <f???????
2009/10/22 21:39:32 [3820] sent 28836048 bytes received 61235 bytes total
size 29028217
As you can see, roughly 30 MB are transmitted.
2) Incremental backup:
2009/10/22 21:40:46 [3940] 192.168.5.9 is not a known address for "localhost":
spoofed address?
2009/10/22 21:40:46 [3940] connect from UNKNOWN (192.168.5.9)
2009/10/22 21:40:57 [3940] rsync on . from baggub@unknown (192.168.5.9)
2009/10/22 21:40:57 [3940] sent 212 bytes received 674 bytes total size
29028217
Almost nothing is transmitted, as the client only checks the timestamps.
3) Another full backup: This looks exactly like the output to 1). All data is
sent over the wire again. Rsync summary states that about 30MB are transmitted.
4) Experiment:
For testing, I added "--checksum" to the {$RsyncArgs}. I rerun a Full Backup
again:
2009/10/22 21:55:09 [2172] rsync on . from baggub@unknown (192.168.5.9)
2009/10/22 21:55:10 [2172] send unknown [192.168.5.9] docsnsettings (baggub)
.musikproject/musikCube_u.ini 1913 <f???????
2009/10/22 21:55:11 [2172] send unknown [192.168.5.9] docsnsettings (baggub)
.musikproject/musik_collected_u.db 157696 <f???????
2009/10/22 21:55:11 [2172] sent 158068 bytes received 762 bytes total size
29028217
Interestingly, this time, only the two small files get retransmitted, the big
one is left out.
I then restored my configuration to include the complete client pc, keeping the
--checksum parameter. Sadly, now all I get is fileListReceived errors on the
server, so this didn't help either.
And for the records, I tried both rsync 2.6.8 and 3.0.4 on the client.
Craig, is this expected behaviour? Why does the full backup retransmit
everything everytime?
Thanks
Harald
