Copying XFS Filesystems With xfs

Copying XFS Filesystems With xfs_copy

The xfs_copy command can be used to copy an XFS filesystem with an internal log (XFS filesystems with external logs or real-time subvolumes cannot be copied with xfs_copy). One or more copies can be created on disk partitions, logical volumes, or files. Each copy has a unique filesystem identifier, which enables them to be run as separate filesystems on the same system. (Programs that do block-by-block copying, such as dd, do not create unique filesystem identifiers.) Multiple copies are created in parallel. For more information, see the xfs_copy(1M) reference page.

An example of the xfs_copy command is:

# xfs_copy /dev/dsk/dks0d3s7 /dev/dsk/dks5d2s7
... 10%  ... 20%  ... 30%  ... 40%  ... 50%  ... 60%  ... 70%  ... 80%  ... 90%  ... 100%
Done.
All copies completed.
