Backup not completing

I'm not able to complete my Managed backup, it fails on 10%

First, it was returning "Other Kind or error" now just "0"

Tried to use

/* Snapshot Settings */
define('SNAPSHOT_FILESET_CHUNK_SIZE', 10);
define('SNAPSHOT_TABLESET_CHUNK_SIZE', 100);
define('SNAPSHOT_FILESET_LARGE_FILE_SIZE', 104857600); // skip files over 100mb
/* End of Snapshot Settings */

But not working too, can you please, help me?
