Hello - I've been trying to back up my entire Minix 1.3d system to floppy, preparatory to upgrading to Minix 1.4. I was planning to use PDTAR and 'vol' to (a) maintain links in the filesystem and (b) split it among multiple floppies. Attempts to have PDTAR send to standard output fail in weird and hard to replicate ways. While it will accept: pdtar -c -v -f - file1 file2 and fill my screen with those files, it gets unhappy with: pdtar -c -v -f - file1 file2 | vol 1200 /dev/at0 and complains that "-" is too large a file for it to save. Sometimes the failure causes a logout and lots of "login:" messages. I can't seem to compile this thing with the 1.2 cc compiler binaries; there is a structure definition missing from line 373 of create.c . Before I even attempt to figure out PDTAR, has anyone else solved this problem? Regards, Mark Becker mbeck@wheaties.ai.mit.edu
