ASE slow performance on backup

Hello Guys,

I need your help regarding the performance of ASE during backup.

My os is WINDOWS on vmware. When I perform a dump of database (my db is 350 GB) it takes 7 hours to complete.

There's a way to optimize it?

Prefer to avoid the use of QUIESCE method. From what I read it does not allow the update on tables and my SAP system must be up during backup (correct me if my assumption is wrong).

Any suggestion?

Some parameter I can change to optimize it?

Is it related to disk?

Please let me know.
