? CMP-Disk, Storage_Management, Realtime Compressing virtual disk   F Need to store a lot of archival information online and lack the space?A This utility can save factors of 3:1 in storage space for any VMS  file structure.   : This area contains a compressing VMS disk for Vax or AlphaA (cmphighc.zip), Alpha versions of disk drivers for remote virtual < disk over DECnet and host processes, and for files stored onD somewhat encrypted files on local disks. The remote disk can be usedB for remote backup or access and will attempt to recover if the net link fails.   < Also present are some other odds and ends, and the SPD for aC user undelete (reliable, this one) and enhanced VMS security module  called SAFETY from the author.  $ You are requested to read this also.  D The compressing disk works by taking a compressed image of an entire@ disk in a utility. The virtual disk driver (called dtdriver) andA server program communicate to present the compressed image to the @ system as a readonly disk whose storage occupies normally 1/2 orE less of the blocks the original disk does. For databases, the savings B can be even more impressive. The containers can be accessed across* DECnet from many sites at once if desired.  A Either of two algorithms may be used...a blindingly fast one, for B slow VAXen normally, or the zlib (zip) one which compresses better- but is slower. Build it for the one you want. 
