“Backup Copy
“From Adobe reader (for Android)’s end user license
agreement:“3.3 Backup Copy. You may make one backup copy of the Software,
provided your backup copy is not installed or used other than for
archival purposes.“Which leads one to inquire what, if any, point is served by a
“backup” copy which can only be “installed… for archival
purposes”.”
