## NAME
       xfs_rtcp - XFS realtime copy command

## SYNOPSIS
       **xfs**___**rtcp** [ **-e** _extsize_ ] [ **-p** ] _source_ ... _target_
       **xfs**___**rtcp** **-V**

## DESCRIPTION
       **xfs**___**rtcp** copies a file to the realtime partition on an XFS filesystem.  If there is more than
       one _source_ and _target_, the final argument (the _target_) must be a directory which already  ex‐
       ists.

## OPTIONS
### -e
              Sets the extent size of the destination realtime file.

### -p
              destination filesystem. When **-p** is specified **xfs**___**rtcp** will pad the destination file to
              a  size  which  is  an  even multiple of the filesystem block size.  This is necessary
              since the realtime file is created using  direct  I/O  and  the  minimum  I/O  is  the
              filesystem block size.

### -V

## CAVEATS
       Currently, realtime partitions are not supported under the Linux version of XFS, and use of a
       realtime partition **WILL** **CAUSE** **CORRUPTION** on the data partition. As such, this command is made
       available for curious **DEVELOPERS** **ONLY** at this point in time.
