What is the scenario that they guard against today? I claim that they don't do this anymore.
Scenario 1: 1) Save, which succeeds 2) Do some work, but don't hit save 3) KiCad crashes Result: data after last save is lost Scenario 2: 1) Save, which succeeds 2) Do some work, hit save 3) KiCad crashes while saving file Result: The same as Scenario 1, since my recent change to save behavior. -Jon On Tue, Jun 30, 2020 at 11:09 AM Andrew Lutsenko <anlutse...@gmail.com> wrote: > > I don't think removing the current backup system before implementing a new > one is the right thing to do. > As limited and simple as it is, the current system provides valuable > safeguard against data loss on crashes that may corrupt the main save file. > And no, VCS is not a replacement, most people hit ctrl-s a lot more often > than they do "git commit". > > > On Tue, Jun 30, 2020 at 7:13 AM Jon Evans <j...@craftyjon.com> wrote: >> >> JP, I agree that true backups are useful. >> >> Maybe even it is a good idea for KiCad to have a built-in backup function. >> >> I just don't think the current backup function is actually useful >> because of my first point (backups are overwritten on each save). >> >> I would propose: >> >> 1) Remove the current backup file generation >> >> 2) Create a spec (in GitLab issue) for a better backup system that: >> >> - Can be turned on or off >> - Backs up the whole project in a zip file >> - Can keep the last N backups >> - Runs on a schedule, not necessarily every time you click Save. >> >> Anyone opposed to this? >> >> -Jon >> >> On Tue, Jun 30, 2020 at 3:32 AM jp charras <jp.char...@wanadoo.fr> wrote: >> > >> > Le 30/06/2020 à 00:13, hauptmech a écrit : >> > > >> > > While I agree that it is not KiCad's job to do archival backups or >> > > version control, I do think that KiCad should preserve the integrity of >> > > users data through a crash.
