- ams6110 16y agoIt's been a LONG time since I've used VMS, but I'm pretty sure that the file versions were just complete copies of the prior version of the file, not deltas as any modern VC system would keep, and there was a limit (perhaps configurable) e.g. you'd have up to the last 10 versions of your file, but not the entire history since creation.
- michael_dorfman 16y agoThe versions were indeed complete files and not deltas. The limit to the number of files kept was a user-configurable setting, and there was a series of commands (like PURGE) to get rid of unwanted versions. (There was also an optional directory size quota, to limit disk usage by users.) Obviously, it would take a bit of jiggering to alter the system to use deltas-- but you'd think that there would have been ample opportunity in the past few decades for someone to do that work, if desired.
