概要

Back an app up into one zip that lands in the user's own Downloads folder with no storage permission, keeping only the newest N archives. Covers checkpointing the database's write-ahead log before the file is copied, assembling the archive in cache first, inserting through the system media store, and pruning old archives with a query over that same collection. Android only. Use when a restored backup is missing the most recent writes, when the backup file is invisible to the user's file manager, or when old backups accumulate forever.

Backing an app up to a zip in the user's Downloads

Android only. Three moving parts, and the order between them is the whole feature:

Checkpoint the database's write-ahead log (WAL), then copy the database file.
Assemble the zip into the app's own cache directory.
Stream that temp file into a row you insert in the system media store, then prune.

Checkpoint, then copy

A database in write-ahead-log mode keeps recent commits in a side log, not in the main database file. Copying the file alone gives you a database as of the last checkpoint — the copy silently omits everything committed since. Ask the database to fold the log back in first:

// adapted — inside the archive builder, per entry
val settingsFile = File(context.filesDir, "datastore/$SETTINGS_FILENAME.preferences_pb")
if (settingsFile.exists()) {
    zip.putNextEntry(ZipEntry("$SETTINGS_FILENAME.preferences_pb"))
    settingsFile.inputStream().buffered().use { it.copyTo(zip) }
    zip.closeEntry()
}

// Checkpoint BEFORE reading the database file
repository.databaseDaoCheckpoint()
FileInputStream(repository.getDatabasePath()).use { input ->
    zip.putNextEntry(ZipEntry(DB_NAME))
    input.copyTo(zip)
    zip.closeEntry()
}

The checkpoint itself is a PRAGMA wal_checkpoint(full) issued through the ORM's raw-query escape hatch. That escape hatch has its own connection trap — see the sibling skill room-rawquery-readonly-vacuum, which covers which statements a raw query may and may not run.

Optional payloads (a media cache database, a downloads folder) go in behind their own flag, each guarded by an existence check, because a user who never downloaded anything has neither.

Insert into the media store, do not write a path

Writing to a public directory by path needs a storage permission. Inserting a row into the media store's downloads collection does not — the system creates the file for you and hands back a URI you write through:

// adapted
val values = ContentValues().apply {
    put(MediaStore.Downloads.DISPLAY_NAME, "backup_$timestamp.zip")
    put(MediaStore.Downloads.MIME_TYPE, "application/zip")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        put(MediaStore.Downloads.RELATIVE_PATH, "Download/<AppFolder>")
    }
}
val uri = resolver.insert(MediaStore.Downloads.EXTERNAL_CONTENT_URI, values)
uri?.let { out ->
    resolver.openOutputStream(out)?.use { sink -> tempZip.inputStream().use { it.copyTo(sink) } }
    true
} ?: false

Traps

Every read of the database file needs its own checkpoint; every write needs a close as well. The scheduled worker and the manual export are the read direction, and they share the pair above: checkpoint(), then copy the file out. Restore is the write-direction sibling, and it needs one more step — checkpoint(), then closeDatabase(), then overwrite the file. Forget the checkpoint on a read site and you get a backup that is almost right, which is the hardest kind to notice. Forget the close on the write site and the overwrite lands underneath a live connection that still holds the replaced file's pages and its own log; restarting the process immediately after a restore, as both platforms here do, is part of the same precaution, not a substitute for it.

RELATIVE_PATH does not exist below the scoped-storage API level, and neither the insert nor the retention query may use it there. Both sites need the same version branch, or the prune runs a selection over a column the provider rejects and cleans nothing. Wrap the prune so that failure is at least recorded — a caught-and-logged provider error is the only trace you get, since nothing about it reaches the user and the symptom is merely that old archives never stop accumulating.

The retention query keeps the newest by sorting, not by comparing timestamps. Sort descending by date-added and drop the first N; everything left over is old. Flip that sort and you delete exactly the archives you meant to keep:

// adapted
val sortOrder = "${MediaStore.Downloads.DATE_ADDED} DESC"
…
if (backups.size > maxFiles) {
    backups.drop(maxFiles).forEach { (id, _) ->
        resolver.delete(ContentUris.withAppendedId(EXTERNAL_CONTENT_URI, id), null, null)
    }
}

The LIKE selection is not the identity check. The cursor loop re-tests the name's prefix and suffix before adding a row to the delete list. A LIKE pattern is a wildcard match over a column other apps also write to; the second check is what stops the prune reaching a file you did not create.

Assemble in cache, then copy. Building the zip straight into the media-store output stream means a failure mid-archive leaves a truncated file already visible to the user in Downloads. The temp file is deleted after the copy attempt either way, and retention runs only when the copy reported success.

A disabled feature must return success, not failure. The worker re-reads its own enabled flag and returns success when the feature is off; only a genuine save failure returns retry. Returning failure for "user turned it off" burns the retry budget on nothing. Why the worker re-reads a setting the scheduler already observed is covered in datastore-driven-workmanager.

Verifying it

Find every place the database file is opened as a file and check each one checkpoints first. Grep the repository's own accessor, not the bare name — the platform's unrelated Context.getDatabasePath(name) shares that name, and so do the accessor's own declaration and its per-platform implementations: grep -rn "<repo>\.getDatabasePath()" --include='*.kt' <src>. Every hit that goes on to open a stream must have the checkpoint above it in the same block — and, on the write ones, the close too. A hit that only stores the path in a field is not a copy site.
Restore onto a fresh install and check for the last thing you did before backing up. A missing checkpoint costs you only the newest writes, so a stale-looking-but-plausible restore is the symptom.
Open the file from the device's own file manager, not through the app. A file written without a media-store row exists on disk but never appears there.
Run the schedule past the retention count (temporarily lower it) and confirm the survivors are the newest, by name and by date.
Run the whole thing once on a device below the scoped-storage API level, or at least force the else branch — it is the branch nobody exercises.

# Backing an app up to a zip in the user's Downloads

Android only. Three moving parts, and the order between them is the whole feature:

1. **Checkpoint** the database's write-ahead log (WAL), then copy the database file.
2. Assemble the zip into the app's own cache directory.
3. Stream that temp file into a row you insert in the system media store, then prune.

## Checkpoint, then copy

A database in write-ahead-log mode keeps recent commits in a side log, not in the main
database file. Copying the file alone gives you a database as of the last checkpoint — the
copy silently omits everything committed since. Ask the database to fold the log back in first:

```kotlin
// adapted — inside the archive builder, per entry
val settingsFile = File(context.filesDir, "datastore/$SETTINGS_FILENAME.preferences_pb")
if (settingsFile.exists()) {
    zip.putNextEntry(ZipEntry("$SETTINGS_FILENAME.preferences_pb"))
    settingsFile.inputStream().buffered().use { it.copyTo(zip) }
    zip.closeEntry()
}

// Checkpoint BEFORE reading the database file
repository.databaseDaoCheckpoint()
FileInputStream(repository.getDatabasePath()).use { input ->
    zip.putNextEntry(ZipEntry(DB_NAME))
    input.copyTo(zip)
    zip.closeEntry()
}
```

The checkpoint itself is a `PRAGMA wal_checkpoint(full)` issued through the ORM's raw-query
escape hatch. That escape hatch has its own connection trap — see the sibling skill
`room-rawquery-readonly-vacuum`, which covers which statements a raw query may and may not run.

Optional payloads (a media cache database, a downloads folder) go in behind their own flag,
each guarded by an existence check, because a user who never downloaded anything has neither.

## Insert into the media store, do not write a path

Writing to a public directory by path needs a storage permission. Inserting a row into the

    put(MediaStore.Downloads.DISPLAY_NAME, "backup_$timestamp.zip")
    put(MediaStore.Downloads.MIME_TYPE, "application/zip")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        put(MediaStore.Downloads.RELATIVE_PATH, "Download/<AppFolder>")
    }
}
val uri = resolver.insert(MediaStore.Downloads.EXTERNAL_CONTENT_URI, values)
uri?.let { out ->
    resolver.openOutputStream(out)?.use { sink -> tempZip.inputStream().use { it.copyTo(sink) } }
    true
} ?: false
```
