I worked at client site which had about 100+ production instances running on
HP-UX .
We had a DR exercise every 6 months . We used to compress the archive file
always
and uncompress them before doing recovery . I understand now that RMAN would
not back it up .
Our backup solution obviously did not include RMAN . I honestly have not
encountered a problem
uncompressing the archives . But again i could be just lucky .
