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.

December 25, 20232 yr Author 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
December 26, 20232 yr Author 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?

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.
