switching from uncompressed to compressed

[Guenther Bergmann]

Hi *SMers,

if i change a TSM nodes setting from compression no to
compression yes, will i be able to restore both compressed and
uncompressed data using the same options file?

What should i keep in mind when switching from
compression no
to
compression yes
?

Thanks in advance

regards Guenther

Though compression is a node option, it is not necessarily the case
that all files backed up by the node are compressed, as is evident by
the COMPRESSAlways option and the available EXCLUDE.COMPRESSION
option. This indicates that compression is an object attribute.
(There is no way of querying it that I know of, however.) Thus, the
restorability of a given file is independent of the current node
compression option.
