Cron pattern to copy over a USB drive
-
True, it's applicable on any other Linux system - and you provided adequate notice that it's a bad place to make a mistake!
-
@phildunlap Hi Phil! Thanks for your advice.
When I try to give that path to the backup directory I get an error:
-
Did you see over SSH or Webmin if the device is actually mounted there? 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/ -
@phildunlap On Mango I'm logged in with admin.
The mounting point is owned by root.
-
Try chown'ing that to the 'mango' user like,
sudo chown -R mango:mango /media/usb* -
@phildunlap I don't have permission to change the owner for /media/usb0/. Could be a problem because the USB is mounted there?
-
I wouldn't think so. Did you sudo? What response did you get from running the command?
-
I edited the command, as there was no reason to give the mango user access to /media/boot/
-
This is the command and the error:
-
It could be caused by the filesystem type not supporting Linux permissions. Perhaps you could reformat the drive to an ext3 or ext4 filesystem?
-
@phildunlap I get same error in mango and the drive is formatted as ext4, is mounted and the mango user has wrights to write on the usb0 folder.
-
Hi guys, just gonna give a suggestion, cd into /media/usb0/
then do the chown againsudo chown mango:mango . -Rthen enter the
ls -laThat 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 -
Also ensure the mango user has at least read permissions to /media

You're logged in as root, you need to be the mango user if you want to test effectively, also please use those code tags, it makes a lot easier to read.
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.Fox

Perfect, try doing backups now with mango
-
ok, now worked, I can use that path and my back-up was saved there.
Also 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?

Nicely Done!

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.

ok, Thank you a lot!
