[dumps] Review backup strategy
Closed, ResolvedPublic


The dumps cloud vps project instances are quite heavy (500GB each), currently we are experiencing a shortage of storage for the backups so we have to figure out what's the need (if any) and to what degree we want to backup those vms.

@Nemo_bis, @Hydriz: as admins of the project, can you give insight on what's stored on the VMs and what's the impact of losing one of them? Thanks!

Event Timeline

Thanks for creating this task. Currently, dumps-1 to dumps-5 do not need to be backed up at all (especially @Andrew mentioned in T159930#5234371 that we should delete and re-create the instances often). Likely in the future, any instances of dumps-[1-9] do not need any backups (or really any instance with the type dumps-temporary-file-storage).

However, dumps-0 is the one that holds important data, that instance should be backed up if possible.

Awesome, thanks! I'll do that then in the next patch :)
