<![CDATA[Cron pattern to copy over a USB drive]]>Re: NoSQL Offsite Backup

Hi everyone, I see in the topic from above that is possible to insert a USB drive into the MangoES box and create a cron pattern that will copy automatically the files from the backup directory over the USB drive.

I'm quite novice in this area and if anybody can help me with more information about how I can do this and how I can run this cron pattern it will be very helpful.

Thank you!

ok, now worked, I can use that path and my back-up was saved there.

Nicely Done!

lso I have a question, this feature of writing directly the location of the USB drive into the Backup Directory works only in V3? In V2.8 is it working or not?

It'll work in both instances as long as your directory permissions are set correctly. Under the hood mango V2 and V3 are still running java, V3 just has a new shiny interface.

Edit: Thanks!
Ok dir permissions look good. Try doing the touch newfile as mango, if you can do that, there should be no issues with mango creating files. I'll check my server for you soon if wanted to compare configs.

then do the chown again

sudo chown mango:mango . -R

then enter the

ls -la

That should give us all info for that directory to start. Skywatcher, assuming you are using putty if you highlight the text, you can then paste into here with code tags.

You should be able to create a file just with touch file
no sudo required

Perhaps you could reformat the drive to an ext3 or ext4 filesystem?

sudo chown -R mango:mango /media/usb*

The mounting point is owned by root.

It could also be a permissions issue, if Mango is running as a non-root user but that mounting point is owned by root. Check with ls -l /media/

When I try to give that path to the backup directory I get an error:

Wasn't entirely sure on if fstab was applicable but felt it was good enough to mention for how a linux fs works at least.

You shouldn't have to worry about mounting the USB drive with fstab as Fox suggested - V3 Mango ES units have usbmount installed to facilitate the USB Utilities actions. It will mount the first USB stick plugged in at /media/usb0

After that, your choices are

  1. Set Mango to backup directly to the USB drive instead of to the /opt/mango/backup folder. This is in the system settings
  2. Set up a cron pattern as Fox suggested and add that to a crontab either via crontab -e to invoke the script or simply add the script /etc/cron.daily/ (and then you don't need to generate the cron pattern but you have less control).
  3. Set a schedule in Mango and use event handlers to copy / move files as necessary.

https://linux.die.net/man/1/rsync
Rsync can also delete the source files after they have been copied over if needed, however mango should do that for you if you've got a rolling backups of N days.
Also take note you are better off making a bash script so you can run some checks. IE if the file system exists (the usb I mean)
Make sure the bash script starts with

#!/bin/bash

Use https://crontab-generator.org/ to generate the cron pattern you'd like to use.
Finally:
Look at fstab for automatically mounting the USB file system and giving it a friendly name under mount if applicable - not necessary though
https://help.ubuntu.com/community/Fstab

Read up on that first and make sure everything lines up before restarting the mango , it can throw a spanner in the works if Linux doesn't like the fstab configuration.

Once you've had a read I can assist further
