Backup encryption + zlib = mess
Being a big fan of both encryption and disk-based backups, I decided to try simultaneously encrypting and (undocumented) compressing a save set, like so:
BACKUP *.TXT SAVESET.SAV/SAVE /DATA_FORMAT=COMPRESS /ENCRYPT=NAME=MYKEY
The result?
%BACKUP-I-COMPRESS, data compressed by 0%
HP is encrypting the data before compressing it. If they did the reverse, there would actually be some compression. Now how the heck do I recommend a fix for an undocumented feature before it becomes official in, I guess, 8.3-1?

Re: Backup encryption + zlib = mess
As a note, it is possible to use only compression first, then ENCRYPT the saveset file; but that has the disadvantage of displaying errors as if the save set was corrupted if you forget to decrypt it first.

Re: Backup encryption + zlib = mess
Guy Peleg e.g. on his TUD speeches has told, that compression and encryption is currently not supported.
