For now, I'm fine with allowing Google/any other big company to manage my email; however I'd prefer to keep my storage documents/photos/contacts out of the storage of third party companies.

I'm looking for solutions that I can deploy on my own servers, preferably open source, and should auto sync a majority of these categories: (photos, documents, contacts, general storage).

I'd really love if the client supports certificates as well.

Could you also suggest corresponding opensource Photos Gallery apps?

You can use Nextcloud. I'm currently using its predecessor Owncloud for quite some time for syncing my Android with my PC. Nextcloud was forked from Owncloud about half a year ago and it seems like it will be more intensively developed in the future.

It is Open Source and clients and third-party apps exist for most platforms. With the webapp you can edit documents and have a photo gallery included. You can also share files or folders with a link.

It can sync ...

  • Contacts
  • Calendars
  • Tasks
  • Notes
  • Newsfeed (optional plugin)
  • Files/Photos

On the Android Site you can use DAVdroid to sync contacts and calendars (available for a small donation on the Play Store and for free from FDroid Store) and Notes for syncing ... right, Notes.

For File Sync you can use the official Nextcloud app or use any webdav compatible Application. (e.g. Keepass2Android can directly access a keepass2 (kdbx) file via webdav)

A search for Nextcloud on FDroid gives some more possible apps.

  • Nextcloud doesn't has 2 way sync yet!
