Your #1 is why I gave up on cryptomator. I was using it in conjunction with GoodSync, but it was way too slow and impractical for large numbers of files. I’ve tried every free and open source solution, including a few paid ones with encryption, like SyncBack and GoodSync. Overall, I decided on CrococryptMirror. It is free, fast and has sync built in. Does 256AES encryption, obfuscates file & folder names, and mounts encrypted volumes easily. The 2 downsides are there is no mobile version (not a big deal for me) and it uses Java Runtime, which has a memory leak, so after a day or two of sync activity, bloats memory usage over a gig, so you have to re-start crococryptor.
I’d like to see a better all-in-one solution that has:
- Cloud integration
- Sync built-in
- Encryption of files & file names
- Multi-destination sync (to local and cloud for same volumes
- Mountable backups
- Mobile access
- Open source code
Haven’t found anything that comprehensive yet.
