Is there another or better way to do this? I have done some experimenting and it is cpio that is dumping core. This happens at the same place in my test files on both our Sun 3 and Sun 4 running 4.0.3 when listing the files in the archive using cpio -itvc <archive # archive is ~20MB in this test After listing about 670 files containing about 6.7MB I get a segmentation fault/core dump. Am I doing something wrong here or is there a problem with Sun cpio and/or OS? Isn't this the kind of thing people need to do with cpio all the time? I received no suggestions from anyone about how multi-volume compressed backups could be done. Is it not possible without having sufficient disk space to store the intermediate file? Thanks!
