We have ORACLE 9ir2 on DELL server. we normally keep two weeks RMAN backup on disks (include full and incremental). Due to database big, we plan to compress RMAN backup use "gzip". My questions are: 1. does "gzip" will hurt RMAN backup data or not? 2. if I "gunzip" RMAN backup, can it restore without ANY problem? Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com -- //www.freelists.org/webpage/oracle-l
