Btrfs File System
Set usage quota and user quota on shared folders.
Enable file compression for more efficient volume usage.
Perform defragmentation to increase system performance.
Data checksum is enabled by default and data scrubbing can be run to verify data integrity.
When file versioning is enabled in Cloud Station, it will not occupy additional storage, which would be the same amount of size as each shared folder.
Files will be backed up at the point in time when a backup task is started, even if the files are changed or deleted afterwards.
It is not supported to convert existing ext4 file system to Btrfs. You need to create a new one and move files on your own.
