Backup encrypted folder to cloud?

[hakest]

One of my folders in TOS6 is encrypted. Now I wonder how to backup the encrypted data (files?) to a cloud drive. Is there any way to achieve that by simply copying the encrypted data?

Restrictions:
- My cloud service is not listed in CloudSync etc.
- rsync with SSH could not be configured via the TOS UI. I managed it to configure planned tasks with a rsync command and a key stored on the cloud drive.
- Mount the cloud drive as SMB with the TOS UI did not work. Mount it as WebDAV is possible.
- Therefore TFM Backup could be an alternative.

Currently I zip some of the encrypted sub-folders password protected with an additional command in a planned task prior rsync them with my cloud for a backup.

Did I missed something?

Encrypted backups to the cloud help you maintain security while ensuring data accessibility. Use a trusted cloud service that supports encryption and verify your backup process regularly to avoid data loss.
