Data erased from iPAQ hx4700
If an ipaq loses power , then all data in RAM is lost. It's important to keep it charged.
It's also important to do regular backups.....
so there are two backup options - one is thru Activesync which will backup to your PC and one is the IPAQ's own backup program which will backup to the IPAQ FILE STORE (area in ROM) or a SD card.
I do the Activesync backup every time I sync and then the IPAQ backup about once a week or immediately before a system change.
Here is a guide which best explains it
this guide suggests doing a full backup, but it's fine to do an incremental backup each sync - this means that only changes will be added to your backup and makes the whole process much quicker.
So under Programs is a program called IPAQ Backup. The default location is IPAQ FILE STORE which is an area in ROM and is not lost thru a power failure nor hard reset.
You may also choos to backup to a SD card - a full backup will need roughly 20MB. So in this backup procedure, if you click on 'Browse' you can choose a SD card.
A restore can then be performed from the IPAQ FILE STORE or SD card (depending on which location you chose) and so if you are away from your PC, this will be no problem. A restore this way , rather than thru Activesync is also much quicker, so if you have a choice go this route.
