Did things like compress 4  G listing CDs to one physical one, etc. etc. Look for something in one of  my directories named c*.zip.  F I have not fixed it up for IA64 boxes but it will run on vax or alpha I and complete source is there. The better of its 2 compression algorithms  F uses zlib. cmpdsk*.zip may be the correct name; I don't have the indexH up just now and don't recall exactly. I have used it rather extensively H and it has not failed except briefly when I tried using it with VMS 7.3 G with XFC cache, and hit a VMS bug that was failing to handle split I/O  C correctly. That was fixed in 7.3-1 or 7.3-2 (or didn't bite if you  E turned off XFC and used VIOC instead). It is designed also so that a  G compressed disk image (which lives in 2 files, one containing an index  I and the other containing compressed data) can be accessed over DECnet if  @ desired. It will pretend to succeed in writing BTW so that file H structures that insist on r/w mounting should work (ntfs does) but will D not actually write anything. You run a separate compress program to 0 compress a full size disk down to a smaller one.  I NOTE: Please remember that a beast like this, which is keeping chunks of  G disk (32 blocks in this case) compressed together will behave badly if  @ underlying storage fails. If one underlying block goes bad, the D compressed data may be lost and up to 32 blocks of something can be B lost. If the 32 blocks are in indexf.sys, you lose that many file G headers. KEEP GOOD BACKUPS on other media! (That is always good advice  ? but you should be the more aware of it for this kind of thing.)     H The volume size permitted can be anything a VMS disk driver can handle, G i.e., up to a terabyte. There is some reasonable caching in the system  3 too, so it can behave better than you might expect.    Glenn Everhart   ------------------------------  % Date: Sun, 14 May 2006 17:02:15 -0700 ' From: glenn everhart <everhart@gce.com> $ Subject: Re: Compressing backup file& Message-ID: <4467C507.3020207@gce.com>   Steve Matzura wrote:H > I was just thinking about a product I used for compressing not backupsE > but other data for writing to magneto-opticals and thought, data is F > data, why should it not compress a BACKUP saveset, too?

That capability is still in there as well, though D I did not build anything to compress a saveset specifically. A tape C drive might do that kinda/sorta (or anything else that can handle a ? back/physical saveset) so there are some other ways to do this.   F Compressing backup savesets still tends to lose due to the xor blocks G which compress VERY poorly and louse up any adaptive (i.e., almost any  D modern) compression algorithm. The backup block headers tend not to J compress too well either, but are not the horror show that xor blocks are. Glenn Everhart   ------------------------------  % Date: Sun, 14 May 2006 17:45:02 -0400 ' From: Dave Froble <davef@tsoft-inc.com> @ Subject: Re: Itanium tukwila uses alpha team, EV7 4 core design!9 Message-ID: <PqWdnZb0NvltPvrZnZ2dnUVZ_tWdnZ2d@libcom.com>    bob@instantwhip.com wrote:F > there is hope after all ... the superior team and design won out ... > F > http://www.realworldtech.com/page.cfm?NewsID=361&date=05-05-2006#361 >   I Old news.
