I need to put some order with the photos I take and I receive with my android phone. Just now I use Nextcloud sync client to upload and Photo/Memories Nextcloud Apps to manage photos.
However, I am not very happy with this setup because of the lack of one Android Application for photos and, thus, the photo gallery of my phone is totally different to the Photo/Memories timeline. And photos are not deleted from my mobile phone when I delete them in Photo/Memories. Which selfhosted photo manager do you think is better to backup and manage photos in sync with the phone?
A second question, is it better to manage the photo gallery with a folder structure or with the album functionality of the Photo application? Which is the best interoperable solution? If I use albums in Memories then I can export those albums to Immich, Librephotos… ? Or I would have to create all the albums again after the export?
Round Sync with whatever remote (backend provider) you want supported by the underlying library rclone. They have self hosted remote options like FTP or something. If you want off site and privacy, create a crypted remote pointed to your off site backend remote. It acts as a wrapper to do end-to-end encryption.
Round Sync isn’t in any app store, so I’d set a watcher for releases on Github. You can setup scheduled backups or restores in Round Sync to keep things moving between your phone and backend remote as a relatively set it and forget it for one way syncing.
It has some nuances with bidirectional syncing that can result in data loss if not careful. With your workflow, I recommend something like a daily copy job from your phone to the server. This never deletes files. When you curate your photos via a tool on the backend remote (only do this when all photos on your phone are on the backup server), then you can do a manual sync from the backend remote to your phone to match the two exactly.
Copy just copies or updates to newer versions from target 1 to target 2.
Sync does the same but also deletes any files on target 2 that are not on target 1. Very easy to delete files if not careful in planning out your workflow. Test first.
I use Backblaze B2 for my off site remote which only hides and doesn’t delete files with the default settings. You can manage those with the rclone CLI application on a desktop to later cleanup hidden files or set them to delete after X days or something in the b2 life cycle settings on the Backblaze website.
Its no Google Photos or Dropbox, but it works well enough for me without giving up privacy. It also decouples the syncing from curating of photos giving some additional freedom for a custom workflow.
I personally just have a daily copy job on my phone from my phone to a crypted b2 remote and a cron on my self hosted server to copy from b2 to my self hosted server. Once a year I might clean things up from my server, do a manual sync to b2, then another to my phone. Sometime later I’ll go clean up the hidden (deleted) files in b2.
That said, I care more about backups than bidirectional syncing, so your milage may vary with this solution for your use case.
