[Snapshot Pro] Managed Backup Not Completing

Hello,

Managed Backups do not finish. There is a huge spike in my CPU when the backup starts and then it gets stuck (different place each time).

My php.ini has the following values:

max_execution_time : 500

max_input_time : 1000

memory_limit : 512M

post_max_size : 128M

upload_max_filesize : 128M

I added the following code to my config.php after reading another support thread but with this the backup never progresses beyond 0%

/* Snapshot Settings */

define('SNAPSHOT_FILESET_CHUNK_SIZE', 50);

define('SNAPSHOT_TABLESET_CHUNK_SIZE', 100);

define('SNAPSHOT_FILESET_LARGE_FILE_SIZE', 104857600);

define('SNAPSHOT_FILESET_USE_PRECACHE', true);

define('SNAPSHOT_FORCE_ZIP_LIBRARY', 'pclzip':wink:;

define('SNAPSHOT_ATTEMPT_SYSTEM_BACKUP', true);

define('SNAPSHOT_IGNORE_SYMLINKS',true);

/* End of Snapshot Settings */

Regular snapshot backups run fine.

Can you help please?
