Hi. How would I go about scheduling a daily backup and then either ftping it off to a network share? or copying it to an NFS mount,
My backup file as created using the Backup menu item is 250MB.
I guess it would be best to create the file in a RAM disk or an attached USB stick rather than write this to the SD card each day?
Cheers!
Have a look at this thread
Thanks Ian, I must be missing something - that thread seems to start in the middle of a conversation, and appears to be discussing the development of the backup script?
I’d like to have the script run automatically each day.
Cheers!
I have added this and i can manually run the code, I tried to add it is a cron job but i am unable to get it to run, also this morning the cron job is no longer listed. even tho i ran rpi-rw before hand.
Hi
I can’t help you with that. I used the node red installed with emoncms and set up a daily flow to run the script. Works a treat.

Hi Ian
Do you mind sharing how?

Just import the flow below into node-red, check that the path to dropbox-archive is correct in the exec node, and the backup should run every night at 1.30am (or whatever time you want).
To test - click the inject node, but make sure that you don’t click a second time whilst the first click is still in progress (you can see the PID on the screenshot indicating that it’s still running)

Hi Paul
Thanks for this, i was about 90% of the way. i had the command as /home/pi/data/dropbox/ php backup.php which is wrong.
I have looked at auto backup to usb stick for a while and read about the different propositions.
I went with
$df -h
to find out my usb drive letters sda1
Then i mounted it
$sudo mount -t vfat /dev/sda1 /mnt/usb/ -o uid=1000,gid=100,utf8,dmask=027,fmask=137
Then I
crontab-e to edit cron
I added
0 4 * * 1 /home/pi/backup/emoncms-export.sh
0 5 * * 1 mv /home/pi/data/emoncms-backup* /mnt/usb/Backup/
Is there any reason why restoring this wouldn’t work if pi died, providing I copied the emoncms-backup-2018****.tar.gz back to /home/pi/data/emoncms-backup ?
Regards
M
Backing up to a USB stick sounds a much better option. could a scheduled time and usb device be added in to the backup section?
Paul
You might be interested in this;
Works a treat. And I am pretty sure the file produced is the same as the file created by the built in backup command in emoncms.
Ian
I have used this before and it worked ok. they is just a problem with where it stores the backup in the file system so it fills the SD card and it would only store 5 days on dropbox.
An official backup to usb memory stick would be good, as we could then store many backups on a 16gb usb
Since October 2017 I’ve been using this backup solution using node-red, and with this flow Dropbox will store 30 days worth of backups (even with a free account)
