check / check (push) Waiting to run
A backup uploads its blobs before the manifest that lists them, and the process lock covers one user on one machine, so a prune from another host or user sharing the destination deleted a running backup's blobs. Prune now deletes an unreferenced blob only once its listed time is older than the new config key prune_grace_period (default 24h; a negative value is refused). A newer blob, or one listed with no time, is kept and counted (blobs_too_new). The rclone backend takes each object's time from the listing (use_server_modtime). Decision: a blob a backup reuses from an earlier run that stopped before its manifest keeps its old time and is not protected; the docs and config comments say so. Model: opus-5-5

Short: "Tidy local database and remote storage",

Long: `Removes orphaned data from both the local index database and

|
unreferenced blobs from the backup destination store.
|
|
|
|
Local cleanup drops incomplete snapshots and any files, chunks, or
|
|
blobs no longer referenced by a completed snapshot. Remote cleanup
|
|
scans every snapshot manifest in the destination store, builds the
|
|
set of still-referenced blob hashes, and deletes any blob not in that
|
|
set that is older than prune_grace_period (default 24h). A newer one
|
|
is kept: it may belong to a backup still running, on this host or
|
|
another sharing the destination store, that has not yet uploaded its
|
|
manifest. The grace period does not protect a blob such a backup
|
|
reuses from an earlier run that stopped before its manifest: that
|
|
blob keeps the time of its first upload, so it can be deleted.
|
|
|
|
Snapshot create --prune runs the same cleanup automatically; this
|
|
command is the manual entry point for the same work (e.g. after a
|
|
crashed backup or to reclaim storage). Snapshot remove leaves blobs in
|
|
place; run this command afterwards to delete the ones no longer
|
|
referenced.`,
