Hello, I've a contract opened and opened a clarification ticket but I was requesting to open a case on the forum by veeam support because apparently is not possible to channel this kind of requests via support page (??? my Case# is: 02146796).
My basic question is - given that veeam evolved in a product supporting also tapes and GFS and so opening its use case to a longer term scope:
is it possible to know what is the expected Veeam policy for backup file compatibility between Veeam versions?
i.e. if I archive a backup to tape via Veeam tape system, am I expected to read it on future versions (across major version numbers)?
There is a precise rule that is stated and that will be maintained during software development (so customers can plan accordingly)?
Due to the "recent" inclusion of full tape support in the ecosystem (libraries, vaulting), Veeam system is used indeed also for long term storage / archival of information of files offsite, so the lifespan window of a backup is destined to be longer.
So please in the future consider an official guideline in the documentation and in the development of the software, in order to ease customer planning and risk, regarding the format compatibility across software evolution.
For example something along the lines of the LTO Consortium: a tape drive must be able to read two previous versions (ie LTO7 drive can read LTO5). That of course cover the "physical" medium layer....
So I think that a precise statement or compatibility matrix in the doc affirming something like: "Veeam is guaranteed to be able to read or at least extract files from four major versions before"... this would ease planning, expectation and risk.
