I will be leaving my current job in about 4 months due to graduation from school. I currently have about 20 meg of goodies in my account. A lot of it is source and other important information I have saved away. I would like to dump all of this to a tape and take it with me when I leave. My questions are: Current system: Encore Multimax running BSD 4.2 1) If I dump the stuff to tape using 'tar' will I be able to read it with other machines running Unix or a close derivative of it? 2) I have a copy of source code for 'tar' that is supposedly for a VAX running VMS. Since it almost looks like my next stop with be in a VMS shop will I be able to read the tape in there? (I know I will have to get tar up and running on the VAX first) 3) Since we have a high density/low density tape drive, which is the better format to use? Any comments suggestions on formats to store this information so I will be able to get at it and use it later will be appreciated.

Probably; For me to read it, it would have to have a block size no larger than 8192, since my tape controller has an 8k buffer... I nearly went crazy once trying to read from a tar tape blocked at 20k!!! > 2) I have a copy of source code for 'tar' that is > supposedly for a VAX running VMS.

Or make them run ULTRIX. B-) > 3) Since we have a high density/low density tape > drive, which is the better format to use? Is your drive 800/1600 or 1600/6250 bpi (or even something else, I s'pose)? "Better" is what works. Again, speaking for my own site, I can ONLY read 1600 bpi (which the vendor calls MEDIUM density). I think 1600 is possibly most widespread amongst 9-track drives. > Any comments suggestions on formats to store this information so > I will be able to get at it and use it later will be appreciated. ( IBM EBCDIC ??? Doesn't EVERYTHING read that? }B-) Good luck. -- = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Paul S.
