cron rsync back up weewx

[vigilancewx]

I am trying to back my Weewx directory to a usb drive

If I run the following from the command line it works

sudo rsync -razv  /home/weewx /mnt/usbdrive/$(/bin/date +%m.%d.%Y)

if try to run it as a cron task it fails

 

so I tried to run a more simple cron task

rsync –av /home/weewx/public_html/Dave.html /home/myideas 

 

fails again with

if I run the cron task as

sudo cp /home/weewx/public_html/Dave.html /home/myideas

it works?

so why is rsync not allowing the cron task to run ?

any ideas ?

thanks for any help

EIther a permission thing, or you're writing to a subdirectory that doesn't exist, or both.

You can debug it by running the command, and checking the command exit status (echo $?) which should be zero if it worked and non-zero if it failed.  If it is non-zero you would then look up the exit status in the /usr/include tree. Since you're on a Pi, I'll assume you're running Raspbian, meaning the file to look at is /usr/include/asm-generic/errno-base.h

I find it a little hard to believe that the rsync command you ran from the shell didn't return anything at all.  What you provided was a syslog snippet, not the rsync command writing its thing to standard error (ie, the shell you typed it in).

(example with no read permission) 

rsync -av /root/foobar /tmp/foobar

sending incremental file list

rsync: change_dir "/root" failed: Permission denied (13)

sent 12 bytes  received 12 bytes  48.00 bytes/sec

total size is 0  speedup is 0.00

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1070) [sender=3.0.9]

(example with no write permission)

 rsync -av /etc/motd /root/foobar

sending incremental file list

rsync: ERROR: cannot stat destination "/root/foobar": Permission denied (13)

rsync error: errors selecting input/output files, dirs (code 3) at main.c(583) [Receiver=3.0.9]

rsync: connection unexpectedly closed (9 bytes received so far) [sender]

rsync error: error in rsync protocol data stream (code 12) at io.c(605) [sender=3.0.9]

It seems like rsync returns some strange error codes, but it generally tells you what's going on pretty clearly as the examples above should illustrate.

Hi thanks for your comments

 

Where is the log file

I looked /usr/include/asm-generic/errno-base.h

Yes I have a pi running raspbian

I looked in the errno-base.h

Looks error codes not logs

The directory I am copying to does not have any read or write restrictions

Thanks again for your help

You need to 'do' what I asked for me to help.

Run the rsync command that failed.  Be sure to include the -v (verbose) switch.  It will either tell you verbosely that it worked, or tell you verbosely that it failed (and why).  There are no logs involved when you run from the command line.

If you do this, perhaps I can help.  If you don't, then there's nothing I can do for you.

Hi

Yes your correct its a permissions issue

-v switch reveals all

usb was Fat 32 format

quick search on google

needs to be NTFS or ext3/4

once more thanks for your help

Hi,

Maybe stupid question but when I log in as root on my Raspberry pi with working weewx environment and I run the following command: rsync -avz -e ssh /home/weewx/public_html/ ro...@192.168.178.10:/volume1/web/weather/ the incremental file list is copied to my NAS server without any error. It took some time to understand and implement the Rsync id_rsa.pub. Could you let me know how I can use this command in the weewx environment so Rsync will automatically synchronise my website to my synology webserver?

Thanks in advanced

Michiel

It's pretty well documented in the comments in weewx.conf - edit your values into the [[RSYNC]] section, stop/restart weewx, watch your syslog and see it work hopefully. 

Setting debug=1 might help initially if you don't run with weewx debugging enabled already.

Thanks for your reply.

I works now!!! Just telling me rsynced 57 files.
