Rclone sync just deleted all NextCloud data

What is the problem you are having with rclone?

I ran rclone sync on my server to sync the NextCloud folder. It claimed to find nothing to transfer and deleted EVERYTHING. Nothing ended up in the Proton folder.

Run the command 'rclone version' and share the full output of the command.

rclone v1.75.1

  • os/version: unknown
  • os/kernel: 6.6.x (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.26.8
  • go/linking: static
  • go/tags: none

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

Proton Drive

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

rclone sync Proton:Backup:Nextcloud "/share/Docker/Nextcloud" -vvPaste command here

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

A log from the command that you were trying to run with the -vv flag

2026/10/06 08:59:03 DEBUG : Local file system at /share/Docker/Nextcloud: deleted 11689 directories
2026/10/06 08:59:03 INFO  : There was nothing to transfer

I got the source and the destination the wrong way around. FML.

welcome to the forum,

to protect against that, test using --dry-run


that is not a valid flag.
--vv is a valid flag


not sure that is valid remote?
perhaps Proton:Backup/Nextcloud ?
