Volume

Volumes provide the basic storage space on your Synology Unified Controller. All of your data are stored on volumes. Therefore, before you start to store anything on your Synology Unified Controller, you'll need to create at least one volume. Please note that Synology Unified Controller only supports the Btrfs file system.

Note:

If volumes are used as replicated targets of Snapshot Replication, the replication performance can be improved by adjusting the settings of Record File Access Time Frequency in the Edit window after volumes are created:

  • Daily: File access time is updated daily or when the file is modified, just like in most operating systems. Some applications' functionalities rely on the precision of file access time. Selecting Daily will impact replication performance but is recommended if you use any third-party applications that rely on Record File Access Time frequently.
  • Monthly: File access time is updated monthly or when the file is modified. This option results in a small improvement in replication performance while the applications that rely on Record File Access Time will be able to function, though with lower precision.
  • Never: Recommended if you look for the best replication performance and do not need applications that rely on Record File Access Time in your daily usage.
