Rolling Back a Version of an APP Question?

[TxDoc]

I've seen a couple of references to "rolling back" from an updated version of an app to an earlier one. How is this accomplished?
Thanks

I dunno what other people do, but I sometimes make backups of the .apk on my SD card, and sometimes dump them on my ftp server.

Not all apps can be backed up, but a lot can. All you need is a backup app, or a file manager that has backup support built in.

I usually rename the file to include what revision it was too.

Thanks Luxferro. I see many backup apparently listed in the store. If you can recommend one, I would appreciate it.
Thanks for the reply.
