Please state your Operating System and version. This is going to be O/S specific.
Do you want to copy a Bootable System Partition or a Data Partition?
Can both partitions be mounted (i.e. they are not raw filesystems)?
What is the filesystem type (e.g. VXFS, UFS)?
The general solution for mounted Data Partitions is to use "cpio -p". The switches for cpio vary from O/S to O/S. Some need a large block size (say 64kb) for speed - some don't. The switch for not traversing filesystem boundaries varies too (some are "-mount", some are "-xdev").

xfs_freeze
xfs_freeze(8) System Manager's Manual xfs_freeze(8)NAME
xfs_freeze - suspend access to an XFS filesystem
SYNOPSIS
xfs_freeze -f | -u mount-point
DESCRIPTION
xfs_freeze suspends and resumes access to an XFS filesystem (see xfs(5)).
xfs_freeze halts new access to the filesystem and creates a stable image on disk. xfs_freeze is intended to be used with volume managers
and hardware RAID devices that support the creation of snapshots.
The mount-point argument is the pathname of the directory where the filesystem is mounted. The filesystem must be mounted to be frozen
(see mount(8)).
The -f flag requests the specified XFS filesystem to be frozen from new modifications. When this is selected, all ongoing transactions in
the filesystem are allowed to complete, new write system calls are halted, other calls which modify the filesystem are halted, and all
dirty data, metadata, and log information are written to disk. Any process attempting to write to the frozen filesystem will block waiting
for the filesystem to be unfrozen.
Note that even after freezing, the on-disk filesystem can contain information on files that are still in the process of unlinking. These
files will not be unlinked until the filesystem is unfrozen or a clean mount of the snapshot is complete.
The -u flag is used to un-freeze the filesystem and allow operations to continue. Any filesystem modifications that were blocked by the
freeze are unblocked and allowed to complete.
One of -f or -u must be supplied to xfs_freeze.
NOTES
A copy of a frozen XFS filesystem will usually have the same universally unique identifier (UUID) as the original, and thus may be pre-
vented from being mounted. The XFS nouuid mount option can be used to circumvent this issue.
In Linux kernel version 2.6.29, the interface which XFS uses to freeze and unfreeze was elevated to the VFS, so that this tool can now be
used on many other Linux filesystems.
