Hi
Our HANA appliance file system backups are huge, and I notice the exclusion lists have not been setup.
I would like to confirm the best practice exclusion list, before I request implementation 
We backup via Netbackup interface directly to tape. I noted the HANA Data and Log locations from HANA Studio - Volumes - Storage.
Notes below with my comments:
/sapmnt/data/* ? this directory contains the open database data files – can be excluded from file system backup – this is included in the online full database backup
/sapmnt/log/* ? this directory contains the open database logs (logs are written from here directly to tape by Netbackup interface via log backups)
/sapmnt/shared ? contains the database home – Important to be included in file system backup
/sapmnt/PH1 ? this contains the SAP installation - Important to be included in file system backup
My Question - Should the /sapmnt/log/* file system also be excluded from the file system backup?
I notice the log directory are huge:
jhbtfrlpsha01:/sapmnt/log # du -h *
53G HP1/mnt00001/hdb00004
2.1G HP1/mnt00001/hdb00002.00003
5.1G HP1/mnt00001/hdb00003
49G HP1/mnt00001/hdb00001
2.1G HP1/mnt00001/hdb00002.00004
349G HP1/mnt00001/hdb00003.00004
458G HP1/mnt00001
458G HP1
(almost same size as datafile file system):
jhbtfrlpsha01:/sapmnt/data # du -h *
507G HP1/mnt00001/hdb00004
938M HP1/mnt00001/hdb00002.00003
148M HP1/mnt00001/hdb00003
4.4G HP1/mnt00001/hdb00001
311M HP1/mnt00001/hdb00002.00004
