What is Fast Clone?

Last modified date: 2019-07-11

Fast Clone is a storage feature that enables QES to create copies of files much faster and also save storage space.

Fast Clone works as follows: When you create a copy of a file in the same shared folder or LUN as the original file, QES modifies file metadata so that the original file and the copied file share the same data blocks. This greatly reduces required read and write operations, as QES does not need to write a second copy of the file’s data to disk. Also no additional storage space is needed to store the copied file, until data within the original file or the copied file is modified.

Note: Fast Clone is not the same as Snapshot Clone, which is a feature that enables you to create a copy of a shared folder or LUN from a snapshot. You can use Fast Clone to copy files without needing to take a snapshot of the shared folder or LUN.
