Memory vs Backup

What is the difference between a memory expansion module and a backup module? Thanks.

The backup module backs up the entire content of your Visor memory to a memory chip. You can't run any file from the backup module, however, if you every lose the memory on your Visor (hard reset or battery drain), you simply pop the module back in and it will restore everything that was on you Visor the last time you backed-up...recommended if you are away from the PC to which you hotsynch.

The memory module (depending on the type) lets you individually install programs, data, etc onto the module and run them--like a hard drive.

Close, but not exactly accurate. A memory module lets you conveniently move programs in and out of your handheld units on board RAM. It certainly has more flexibility than the backup module, and is definately a better value. A memory module like Memplug will allow you to run some programs from the module's offboard memory, or provide access to a large database for a program like Tome Raider or CSpotRun. The Visor Deluxe cannot run programs off a module via a program like PI Direct; that program requires Palm OS3.5 or higher to run.

Actually, with regards to the Deluxe, you can download PiVFSMgr from PortableInnovation. It allows you to simulate VFS on Visors running OS3.1 and store VFS Aware applications to Memory Expansion.

PortableInnovation

They have an awesome site now. It has really been updated and is much nicer and easier to navigate.

Well. Close, but not entirely accurate. Using the Flash Module you can run both databases and programs directly from the module with no additional programs and seemlessly, as long as you only use the databases and documents in write-only mode. With the Flash Module, you do NOT need to move files in and out of the Visor's on board RAM to run them.

Out differences in description are based on my assumption of using a Flash Module (the simplest memory alternative) and yours based on a memplug type module. I presumed, behing a newbie, that the author was refering to a Flash Module (which, though relatively costly, I think is still the easiest, most stable memory expansion solution for the Visor)

Which is what I said.

Thanks for the replies. I'm getting the idea that the backup modules are mostly for avoiding disaster. Something I would use when I'm done using my visor for a time. Backup everything in the visor memory just in case something goes wrong before I can get back to my PC. Maybe, even for archiving.

The memory modules are what to use when actually running apps and modifying files.

Have I got it?

Sounds like you have it right except for archiving. With the backup module it is all or none. You can only backup the entire contents of your RAM and when you want to restore you can only restore the entire contents. You cannot choose what to backup or restore. Because of this, it wouldn't be useful for archiving.

It is great for when you will be away from your computer for a while (days) and if you install alot of software of questionable quality and need to go back to a working state!

Mine has saved me a number of times in these cases.

You can use a memory module to do both. You can store apps and databases, and use it as a repository for backup data. If you bought a Memplug and a 16MB card you could backup the entire content of your 8MB Visor, and have another 8MB for app and database storage.
