#343 zip up all files and folders on a drive

[Lynton Washer]

I have a hard disk drive that contains 3 folders some of these folders contain other folders.
i want to use a bat file with 7.Zip to zip them up and store them to another drive using the current date and time as the Zip file name.
I want the zip file to retain the directory structure in case i need to recover drive at a latter date
Drive I: is where the files and folders are now. (all files and folders to be copied)
Drive E: is where i want the zip file to end up. ( Nothing else in E: .Just for these zip files)

my efforts
C:>"C:\Program Files\7-Zip\7z.exe"a" "E:\%date:~-10,2%.%date:~-7,2%.%date:~-4,4%.%time:~-11,2%.%time:~-8,2%" "I:\"

My result
The filename, directory name, or volume label syntax is incorrect.

Any help apreciated

In the command I see, you need to write .exe" a "E: instead of .exe"a" "E:. Otherwise, cmd.exe tries to execute a file named 7z.exe"a. You should also double-check your DATE syntax, e.g. by executing echo E:\%date:~-10.2%.whatever.
