When I got into the PC world many years ago...one of the first words I learned was BACKUP.
Ever since, I have been excessively dilligent in terms of having backup images or copies of key data content on various computer devices.
In some cases, I store image copies, and sometimes they are on either another hard disk or sometimes on a DVD that resides in my safety deposit box for offsite backup. Things like tax documents, photos, and other non-replacable things are good to have stored safely.
This "make sure you backup things important" mentality I have carried over to the ASUS Transformer tablet. It was great to see ASUS include a convenient BACKUP APP that I've used since it was available in the base OS version.
Over the past 90 days, I have maintained a log of backups done using the ASUS BACKUP APP on my Transformer. Since on some days, I have gotten multiple app updates...I have been known to rerun the ASUS BACKUP APP more than once on the same day. While that's likely overkill...I know that at least I have my warm/fuzzy backup safely stored on the microSD card in the event of an app failure. I also copy the backup files to my PC periodically as well.
My test log provided some interesting results when executing a full backup including apps and corresponding app data:
1) Of the 102 ASUS BACKUP APP backups...94 of them ran fine and reported satiafactory completion.
2) 7 of the 102 backups reported 1 App failed to backup successfully among the 82 apps available. Of those, 6 of the failures were for Google Earth, and the other 1 was for the ASUS Webstorage App.
3) On 1 occasion among the 102 backups, 2 apps failed to properly back up (Google Earth and TegraZone).
In all cases, any failed apps were highlighted as such in red on the list for easy identification.
This test seems to confirm that there may still be a few ASUS BACKUP APP anomolies and/or app tweaks needed. 92% of the time, the backup ran perfectly. I also ran restore runs on 10 occasions, and all worked fine.
So the lesson learned for me was; Trust, but Verify...when it comes to running backups.
