Automatic backups with GFS retention

Schedule automatic backups per organization (and per VM or disk) from Backups → Auto-backup. Off by default; turn it on with a retention preset: Basic (keep 3 daily), Weekly (7 daily + 4 weekly), or full GFS (7 daily + 4 weekly + 12 monthly + 3 yearly), plus a time window. Auto-backups go to a DR backend or to Random, which spreads each run across Wasabi and ImpossibleCloud. The scheduler is concurrency-capped and runs in small batches, so a fleet-wide backup window never hammers your VMs.
