From 5e7a61a2551fc9a4805da6e9ada72b567c78eca4 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 6 Jan 2026 05:56:33 +0000 Subject: [PATCH 1/2] Add automated volume snapshots for workspace resilience - Create Fly.io volumes explicitly with auto_backup_enabled=true - Configure 14-day snapshot retention (configurable via FLY_SNAPSHOT_RETENTION_DAYS) - Add volume size configuration (FLY_VOLUME_SIZE_GB, default 10GB) - Add snapshot management methods to WorkspaceProvisioner: - createSnapshot(): On-demand snapshots before risky operations - listSnapshots(): View available recovery points - getVolumeId(): Get volume ID for restore operations - Mount volumes explicitly in machine config Cost impact: ~$0.08/GB/month for snapshot storage (first 10GB free). Incremental snapshots mean typical workspace costs ~$0.50-1.50/month extra. --- ...valuate-flyio-sprites-20260106-062105.json | 27 +++ deploy/workspace/fly.toml | 7 + src/cloud/config.ts | 5 + src/cloud/provisioner/index.ts | 220 +++++++++++++++++- 4 files changed, 258 insertions(+), 1 deletion(-) create mode 100644 .trajectories/evaluate-flyio-sprites-20260106-062105.json diff --git a/.trajectories/evaluate-flyio-sprites-20260106-062105.json b/.trajectories/evaluate-flyio-sprites-20260106-062105.json new file mode 100644 index 000000000..52e726520 --- /dev/null +++ b/.trajectories/evaluate-flyio-sprites-20260106-062105.json @@ -0,0 +1,27 @@ +{ + "id": "evaluate-flyio-sprites-F2Mb0", + "task": "Evaluate Fly.io Sprites offering and implement workspace resilience", + "startedAt": "2026-01-06T05:45:00Z", + "completedAt": "2026-01-06T06:00:00Z", + "decisions": [ + { + "choice": "Keep Fly.io Machines instead of adopting Sprites", + "reasoning": "Sprites are designed for ephemeral AI code execution, not long-running agent sessions.
