Backup to OTG USB

[kare...@gmail.com]

Hi,
I've just started w Automate. Succeeded in writing a backup within the internal storage (Nexus 5X, Android 7) and now I would like write a backup that copies files from the internal storage to an OTG mounted USB flash drive, but I don't see a way to select the Destination Path in the File copy block. Noticed the thread (https://groups.google.com/forum/#!searchin/automate-user/otg|sort:relevance/automate-user/x22iFWOvOug/G143Xud3IgAJ), sadly did not understand. Could anybody kindly help me a bit here, pls?

Best regards,

Karel

"Destination path" is the second field.

Well, thank you... sort of :-) Yes, it is. It is written there. In text. It says "DESTINATION PATH" in capitals :-D My problem is not to locate this input line, but how to fill it so it uses the OTG connected USB flash drive. So far I have only succeeded in using it for manipulating files on the internal storage.

Firstly, you need to give Automate permission to access mountable storage:
Goto 'Settings -> Permissions -> External storage access'
and select the flash drive.

Next, use the block:
File&Storage -> File pick
to select the flash drive.
Make sure you tick 'Directory' for types, then you can use that path to manipulate its files.

Thank you, I did not have the External storage access permission granted. That's done now.
Something still does not work though.
When I choose the PICK PATH, I can navigate using the back arrow to a new root:

/storage
DIRECTORIES
emulated
self

"self" is probably the one I need to go with, but choosing either of them produces "Permission denied" message.

Any idea, pls?

Best,

The path to the USB drive should be something like /storage/XXX-XXX as seen in the External storage access list.

Thank you all. Finally got it to work.
The working solution differs though.
The working path is: /mnt/media_rw/XXXX-XXXX/

I am sorry to being a bother again, but there are still some issues.
I granted the External storage access rights to "/mnt/media_rw/XXXX-XXXX"
When I run the script, the log says in red "...FAIL 67@8 com.llamalab.fs.AccessDeniedException: /mnt/media_rw/XXXX-XXXX/testfile
(where testfile is the file/folder I access and 67@8 part varies w each run)
Does it make any sense to anybody, pls?
Thanks in advance!

/mnt/media_rw/XXXX-XXXX is the system mount point, its the "internal" path which bypass FUSE so it's unlikely apps have access to it.

As said earlier the path accessible by Automate should be at /storage/XXXX-XXXX. See:

Thanks for your reply. The code started to work, probably after a phone restart, but I will look into it again with your information.
Best :)

I gave it another short and probably discovered the reason behind the above mentioned red errors. It appears I need to restart the phone after giving Automate the External Storage Access permission. Until I restart, Automate does not seem to be able to access the OTG USB.
As for the correct path, Icannot help it :(
When I try to use /storage/XXXX-XXXX/ it just doesn't work. Automate cannot access any files that way. The link you used in your answer mentions Android 6. Maybe there were some changes in Android 7, that I use.
Best :)
