Although you can copy data from a system using client programs such as cpio or use the Data ONTAP dump and restore commands, the vol copy command set offers several benefits.
- When a vol copy command reads and writes data, Data ONTAP does not traverse directories on the system. Data is copied block for block directly from the disks, which means that Data ONTAP can finish the copying faster than it could with other methods.
- Using a vol copy command, Data ONTAP preserves the Snapshot copy data of the source volume. If, in the future, users might need to use Snapshot copies that were taken before data was copied from one volume to another, you can use a vol copy command for migrating data. For example, if users accidentally delete files and need to recover them, they can do so from the preserved data.
- You do not need any additional licenses to use the vol copy command.
Maximum number of concurrent volume copy operations: Volume copy has the same limit on concurrent replication operations as volume SnapMirror.
