t looks like cache data don't save back to disk, so the data in cache is gone, then all is gone

It depends on how you have the Shares set up.

 

There are the appdata backup and VM Backup plugins for regular backups of docker container data and VM vdisks for shares configured to stay on the cache.

If you are new to Unraid what is the rationale for running such an old release as it is quite a few years old now and support for it will be limited?   The latest release is the 6.12.6 release.

few years ago, we only have nextcloud requirement, so i add a new docker for nextcloud and simply create a new VM for another purpose ... that's all

then it works fine for years and now the space of cache should be upgraded, i think it's just a cache , then the stupid thing happened...

anyway

 

i found that nextcloud don't setup any cache, how could i recovery the docker of nextcloud?
 

i just try to add new container ,select the template created before, data path is same as the older one(i.e: /data), but it seems not working, my data is not coming back

but i sure that data is in disk, how cloud i make nextcloud  recognize all stored data before

why my /appdata in cache haven't been written back to my disk, i support that it should be written to disk every day...i can't find anything

 

i have three folder set to prefer:cache but "appdata" and "domains" is empty

"system"  has docker.img and libvirt.img

 

if data has been format, Is there any way I can contact the Data Rescue Center to help recover the data in the cache?

The settings you have for the appdata share say it should stay on cache pool and NOT be transferred back to the array.  This is normal as it maximises performance of docker containers.   There is the Appdata Backup plugin available which can be used to make periodic (probably daily) backups of appdata to a specified location somewhere on the array.
