Full Snap Backup

I can not understand whether there is at this time the possibility of a full backup of all the nextCloud installed through snap or not?
If yes, please show me the link to that)
If not, then who has any thoughts about the data?
It may be more appropriate to deploy the environment of the nextcloud witout snap on clean OS and completely with hands. Each component separately? In this case, the process of creating a backup will be easier or vice versa?

Hi, you might be insterested in NextCloudPi.

It features backups and many more features, and it’s easier to modify than Snap because it runs on plain Raspbian.

If there’s interest and help an x86 version could be derived without too much effort
