cpio or tar for migrating file system with > 2Gb files

[Roberto Volsa]

Hello folks
i need to migrate a file system without the use of LVM Mirror.
The usual applicatio i use is cpio (from the local directory to duplicate i launch "find . | cpio -lvdump ).
This does not work with files grater than 2 Gb.
Is tar usefule for this purpose?

Thanks in advance

Hi,

GnuTar can create archives with files up to 8GB.

Hi Roberto:

If this is an HP-UX-to-HP-UX migration, use 'fbackup' and 'frecover'. These utilities handle largefiles without any issues:

# cd srcdir && fbackup -i . -f - | ( cd dstdir && frecover -Xsrf - )

Regards!

I can see that you haven't been following
this argument closely.

GNU "tar" can handle files of any practical
size. See, for example:

Sometimes, using that little "Search:" window
in these forum pages can save some time and
effort.

However, if you're staying on one OS, the
appropriate OS-specific tools (like fbackup
and frecover) are often the best choice.
