```Freezes the current backup, producing the final immutable file set: the BASE snapshot, the incremental append-only file (INCR), and a standalone manifest.

## Examples

```
127.0.0.1:6379> BACKUP SEAL
OK
```

## Details

`BACKUP SEAL` moves the backup state machine from `incrementing` to `sealed`. Restore loads `BASE + INCR`, so the restored dataset reflects the state at the seal boundary, not merely the earlier BASE snapshot. Sealing performs the following steps:

* Flushes and fsyncs the current INCR file.
* Hard-links the INCR file into the backup directory.
* Writes a standalone manifest that references only this backup's `{BASE, INCR}` file set.
* Rotates the live AOF when AOF persistence is enabled.
* Stops and removes the temporary AOF state when the backup created it for an `appendonly no` instance.

After sealing, the file set is complete and immutable. The data plane can copy the files reported by [`BACKUP LIST`](https://redis.io/docs/latest/commands/backup-list), then call [`BACKUP CLEANUP`](https://redis.io/docs/latest/commands/backup-cleanup) to release them.

For the full workflow and restore procedure, see [Redis persistence](https://redis.io/docs/latest/operate/oss_and_stack/management/persistence#online-backups-with-the-backup-command-family).
