The UI could make it *highly* recommended (with some sort of nag) that the user setup a link to Google Drive, Dropbox, or Github.

Re: [sage-support] Re: Sage 5.9
Hi, I don't know anything about http://sage.lacim.uqam.ca/, but I'm starting to get emails directly to me asking for help about it vanishing.Of course, I'll refer people to this thread. Thoughts: This is a very interesting example of how our past approach of encouraging a lot of people we don't know to run random Sage notebook servers all over has the potential to confuse users and significantly harm the reputation of Sage. I had never considered this before. If I had, I might have wanted to have a requirement like: - either (1) don't call it Sage, or (2) we provide a backup system that periodically rsync's a copy of your notebook's file to a central server, just in case. It might be interesting to discuss technically how (2) would work. It could, e.g., pre-encrypt the backups for each user separately using their login credentials as a key, so as long as they can login they could get their data out of this central backup. I will very likely do something like the above with Sagemathcloud, when instances start popping up all over. Make them choose a clearly very different name to avoid confusion, or somehow link with a central service to avoid hurting our poor users. To me the needs of our users are by far the top priority. In particular, though "Stories about student losing against their will "all hard work" make only their teachers smile ...", I think instead that when this happens it is a failure of the Sage community, and we should try to do better. -- William 2015-05-28 12:12 GMT-07:00 Dominique Laurain : > Ouf, > > Merci..a vous pour avoir compris qu'il faut etre rapide... et surtout et a > Franco. > > Attendons un peu avant de crier victoire > > En tout cas, l'informaticien que je suis, va vous rappeler les bases : > FAITES DES SAUVEGARDES VOUS-MEME ET REGULIEREMENT > > Les fichiers SAGE sont en gros des fichiers texte ...si il n'est pas > immédiat de les convertir, ils sont quand meme exploitables sous un éditeur > de texte. > > Et puis organisez VITE votre migration sur le cloud SAGE..dés que le serveur > est reparti, vous téléchargez tout sur votre PC..1er sauvegarde donc...puis > rechargez tous sous le cloud...puis RAPIDEMENT les tests pour voir ce qui > est bon, et enfin pour finir un export en fichier PDF > > Dominique. > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Re: [sage-support] Re: Sage 5.9
Bonjour Ines, Le serveur est au Lacim (Montreal, Quebec). Je ne sais pas qui est responsable de la maintenance la-bas. Il faut chercher directement sur le site du Lacim. Meme sur les notebook en ligne il est possible de sauvegarder son travail sur sa machine personnelle (il faut cliquer sur "save worksheet to a file..." dans le menu "file"). Ce fichier peut alors etre utilise sur d'autres serveurs... et ca fait une sauvegarde! Je ne pense pas que ton travail soit perdu, mais il faut te rapprocher des gens du Lacim. Si tu ne trouves pas, je pense que tu peux contacter Franco Saliola ou bien Alexandre Blondin Massé pour leur demander.
