Remove Duplicates

Excellent! This is my next question.

I’ve already partially synced my Google Photos library by installing Immich on my Android phone and enabling Immich backups. But I see that the oldest photo in Google Photos is way older than what Immich has.

So now I’m worried that when I run immich-go with the full takeout archives, I’m going to get a ton of duplicates because half of my library is already on immich.

What’s the duplicate command? I can’t find it in the CLI…

$ immich-go duplicate --help
Error: unknown command "duplicate" for "immich-go"
Run 'immich-go --help' for usage.
unknown command "duplicate" for "immich-go"

$ immich-go  --help
An alternative to the immich-CLI command that doesn't depend on nodejs installation. It tries its best for importing google photos takeout archives.

  immich-go [command]

  help        Help about any command
  stack       Update Immich for stacking related photos
  upload      Upload photos to an Immich server from various sources
  version     Give immich-go version

Flags:
  -h, --help               help for immich-go
  -l, --log-file string    Write log messages into the file
      --log-level string   Log level (DEBUG|INFO|WARN|ERROR), default INFO (default "INFO")
