* 2: general error: Backup error: Snapshot operations are supported for single tenant systems only. SQLSTATE: HY000
Timeout waiting for HANA DB freeze status!
Hello,
the error message states it clearly... your configuration (multi tenant) is NOT supported for snapshot operations.
Please use BackInt. I know that you already created several threads. I strongly recommend to get professional help. Because doing backup of SAP the way you do it is dangerous for your company if they ever need a restore.
