I have set up a small 1TB NAS appliance, now running on OpenWRT, to back-up files from a small 500Gb drive inside my Devuan Linux box holding all my
The NAS's specs -800MHz APM82181/256MB RAM- require avoiding the use of
ssh or wait ages for a job to complete at 7.50MiB/s max, in spite of both ends having GbE ports negotiating at 1000M.
ssh beats this hardware to death with an almost constant 100% CPU load, mostly due to encryption, so it is not an viable option.
All this is done within a local network with no access from the ouside and I am the only user, so the lack of encryption is not an issue.
With that in mind, I had no choice but to use
rsync as a daemon at the NAS end which would get me at least 3.5/4.0 times the throughput I can get with
The problem is that I am getting an error I cannot find a solution to.
:~$ rsync -av --progress /media/stuff/firefox.oldfile rsync://firstname.lastname@example.org:/stuff sending incremental file list firefox.oldfile 85,812,416 100% 28.23MB/s 0:00:02 (xfr#1, to-chk=0/1) rsync: [receiver] mkstemp "/.firefox.oldfile.hiOlHH" (in stuff) failed: Permission denied (13) sent 85,833,480 bytes received 142 bytes 24,523,892.00 bytes/sec total size is 85,812,416 speedup is 1.00 rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3] :~$
The good news is that 28.23MB/s is (apparently) obtainable. =^)
I have read that this is a permission issue originating in
rsync not being able to write the temporary file
/.firefox.oldfile.dMAADG to the destination folder
The log file adds nothing to the terminal printout:
root@OpenWrt:~# cat /var/log/rsyncd.log  connect from UNDETERMINED (192.168.1.2)  rsync allowed access on module stuff from UNDETERMINED (192.168.1.2)  rsync to stuff/ from UNDETERMINED (192.168.1.2)  receiving file list  rsync: [receiver] mkstemp "/.firefox.oldfile.dMAADG" (in stuff) failed: Permission denied (13) root@OpenWrt:~#
I think my
rsyncd.conf file is correct:
:/etc$ cat /etc/rsyncd.conf # /etc/rsyncd.conf # minimal configuration for rsync daemon # ----------------------- # begin global parameters uid = %RSYNC_USER_NAME% gid = * use chroot = true max connections = 1 pid file = /var/run/rsyncd.pid log file = /var/log/rsyncd.log read only = false reverse lookup = no exclude = lost+found timeout = 180 hosts allow = 192.168.1.2 # use after everything is working properly # port = # set other than default 873 # socket options = # ignore nonreadable = # dont compress = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2 # end global parameters # --------------------------- # begin module parameters # shared folder for testing [testdir] path = /mnt/sda3 read only = false # comment = # shared folder for stuff [stuff] path = /mnt/sda3 read only = false # comment = # shared folder for bkups [bkups] path = /mnt/sda3 read only = false # comment =
The ownership of the destination directories is correct as far as I can make out:
:~$ ls -l /mnt/sda3 drwxrwxrwx 4 groucho groucho 4096 Apr 25 19:03 bkups drwxrwxrwx 2 groucho groucho 4096 Apr 29 18:47 stuff drwxrwxrwx 2 groucho groucho 4096 Apr 28 17:53 testdir :~$ ls -l /mnt
I've been at this for a couple of days now, to no avail.
I'd appreciate it if someone could shed some light on this for me.
Thanks in advance,
