Copying a large file system (again)

[Harald_Jensas at Dell.com]

Hi,

You could use tar and split to create a single large TAR archive that is divided into pieces.

>From this article:
http://www.redhatmagazine.com/2007/10/24/tips-from-an-rhce-splitting-tar-archives-on-the-fly/?sc_cid=3406


create the archive:

tar -czf /dev/stdout $(DIRECTORY_OR_FILE_TO_COMPRESS) | split -d -b $(CHUNK_SIZE_IN_BYTES) - $(FILE_NAME_PREFIX)

extract the contents:

cat $(FILE_NAME_PREFIX)* >> /dev/stdout | tar -xzf /dev/stdin


Regards
Harald
