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.
