Rsync hangs repeatably... and I can't figure out why

[youdigit]

I'm hoping somebody can find something here that I haven't.

I'm trying to use rsync to backup home directories to a nas. First, I NFS mounted the nas and ran an rsync and everything worked out fine... the transfer completed after a few hours and everyting was transferred (lots of stuff!). I then decided that I don't want to leave the nas mounted all the time and I didn't want to automate mounting and unmounting of the nas as I didn't think I could produce a script that would work reliably enough. So I decided to start an rsync daemon on the nas and upgrade via that. I run the following command (results are included... the ^C is me killing it after it hangs).


ryan@server:/etc/backup$ sudo rsync -ax --stats --progress --delete /data root@192.168.0.98:backups1
root@192.168.0.98's password:
sending incremental file list
data/home/user/Documents/
data/home/user/Documents/The File.wmv
2228224 6% 2.05MB/s 0:00:16 ^C
rsync error: unexplained error (code 130) at rsync.c(544) [sender=3.0.6]Before it started hanging on this line, it was transferring updated files for a good while. Now it essentially stops as soon as it starts, always ending when "The File.wmv" (~32MB) is between 6 and 9%. I've checked the permissions/owners/groups on both ends and it is consistent with all the other files that have already been transferred.

I also checked the dmesg on the nas and after the transfer becomes inactive for awhile, the hard drive goes to sleep.

I've tried changing the --delete option to --delete-delay which made no difference. When I tried --delete-after I got the following:

ryan@server:/etc/backup$ sudo rsync -ax --stats --progress --verbose --delete-after /data root@192.168.0.98:backups1

rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]... which I don't understand and haven't found a solution for. So if anybody can shed some light on how to fix this problem I would greatly appreciate it! I'm running a fully updated v9.10.

Thanks!

Some more information: The drive on the nas is basically empty (/dev/sda2). I deleted everything manually and tried again and still got nothing.

Ok, so after screwing around for awhile (as in days) I figured out the problem. The files were copying to the root user's home directory, instead of the defined module. The mistake:


root@192.168.0.98:backups1

should have been


root@192.168.0.98::backups1

I know I tried that syntax at some point in the process, but there must have been another obvious error that caused me to revert back to the original way I did it.

Well done: You solved your own problem! :KS

It would still be good to mark it as "Solved" to help others find this solution in the future.
