[Bug 3116] New: large tar files: 1 gig size: retransmitted: rsync_rsh
https://bugzilla.samba.org/show_bug.cgi?id=3116
Summary: large tar files: 1 gig size: retransmitted: rsync_rsh
Product: rsync
Version: 2.6.6
Platform: x86
OS/Version: FreeBSD
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: drinking.coffee@gmail.com
QAContact: rsync-qa@samba.org
Once a week, I'm performing an offsite backup. These files are each 1 gig in
size, average speedup is 1.18.
Rsync does the initial run, and then send some of the tar files again. I
initially thought the archives were too large, so I reduced them to 512M, but
had the same symtoms. My next step, is to install an rsync daemon on the remote
end.
When I do a second batch of mostly static content, I don't have any issues.
Below are my options:
#!/bin/sh
TERM="VT100"
RSYNC_RSH="ssh -c blowfish -2 -i /usr/username/.ssh/id_dsa"
export RSYNC_RSH
echo ' '
/bin/date
/bin/rsync -lrtv --stats --timeout=300 --delete-after \
/home/backup/psa username@hostname.net:/home/username/backup
source ssh version: OpenSSH_3.9p1
destination ssh version: OpenSSH_3.6.1p2
Output of rsync log:
