Union remote with custom filters

[sntran (Son Tran-Nguyen)]

What is the problem you are having with rclone?

I'm trying to have a union over 2 remotes, but want to have routing on where files should go.

Remote A contains only PDF files.
Remote B contains only XLSX files.

They both have the same below folder structure:

• 2020
  • January
  • February
  • March
    ...
• 2019
  ...
  ...

I would like to have a single union remote named Budget so I can mount and work with all files.
Most importantly, I want to just drop a PDF file in, and it will be transfer to remote A, while a XLSX file will go to remote B.

I have read through the docs for Union remote and I'm not sure it is possible, but I want to ask for help on this.

What is your rclone version (output from rclone version)

rclone v1.53.3

• os/arch: darwin/amd64
• go version: go1.15.4

Which OS you are using and how many bits (eg Windows 7, 64 bit)

darwin/amd64

Which cloud storage system are you using? (eg Google Drive)

Local

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone copy ~/Downloads/December.2020.Paycheck.pdf Budget:2020/December/
rclone copy ~/Downloads/December.Expenses.2020.xslx Budget:2020/December/

The rclone config contents with secrets removed.

[A]
type = alias
remote = /mnt/storage/A

[B]
type = alias
remote = /mnt/storage/B

[Budget]
type = union
upstreams = A: B:

This isn't possible at the moment. The only selections you can have for which union files go to is based on free space or existing directories.

If you had a directory structure like this

• PDF
  • 2020
    • Jan
    • Feb
  • 2019
    • Jan
• XLS
  • 2020
    • Jan
    • Feb
  • 2019
    • Jan

You could make it work by making sure the XLS and PDF directories were only on the corresponding remotes and not on both remotes.
