For what it's worth, I like cpio. I don't know about now, but tar used to have some limitations that make it unsuitable. For example, it used to (don't know about now) have a limit on the number of characters (limit was 80) allowed in a file name that was less that what the OS allowed. I ran into this when tar-ing directories that contained object files generated by the old Rogue Wave C++ stuff. Back in my sys admin days, I found cpio completely reliable for backing up (and restoring!!) entire systems. It reliably backed up and restore ALL file types (pipes, soft links, devices, etc.). >-----Original Message----- >i see various combinations of tar, gzip , dd ... >on the net to do this task. -- To unsubscribe - mailto:oracle-l-request@xxxxxxxxxxxxx&subject=unsubscribe To search the archives - //www.freelists.org/archives/oracle-l/
