> Currently, {{ContinuousBackupReplicationEndpoint}} creates WAL files in the backup location and continuously writes incoming WAL entries.
> These WAL files are consumed during *Point-In-Time Recovery (PITR)* and {*}incremental backups{*}. However, an edge case may arise:
> If we attempt to access a WAL file that is currently {*}empty{*}—for instance, when the *Continuous Backup Replication Endpoint* closes a file, reopens a new one for writing, but has not yet written any data—an exception occurs. The WAL file reader throws an error indicating that the {*}WAL PB magic is missing{*}.
> To handle this, we need to *skip/ignore empty WAL files* and continue processing the remaining files without interruption.
