New to Restic and I think it is fantastic.
What I would like to is this:
I have an Auto scaling Group accessing a ObjectiveFS S3 bucket filesystem backend that I would like to backup using Restic.
I would like the ASG instances to perform this backup. I would like Systems Manager Run Command / Maintenance Window to accomplish this using tags - i.e. Group / Backup or whatever.
My issue is, that normally if you run a second backup after a first, it completes in seconds, however, if you do this on another server - same source and same destination it starts from scratch which I don’t want.
I am assuming Restic has some sort of database it uses to keep track of backups and restore.
What I am looking to do, if possible, is to store this metadata DB on the shared filesystem, have Restic point to it and then when any of my instances (which can get killed at any time) run a backup it will take seconds and do incremental only.
Is this possible? If so, how.
Let me know.
