Disk space usage is greater than 90% - awsbgdnva2010 - Path: /usr/sap   
Issue: 
/usr/sap filesystem on NLS Sybase server (NLS-dbsybsb1) was at 91% usage (28G used / 30G total), triggering a high disk alert. 
 
Root Cause: 
S3 backup log directories under /usr/sap/SYBSB1/sybase/backup/admin/log/ were accumulating daily without any cleanup. Logs dated back to October 2023 — approximately 2.5 years — with 895 old log directories consuming ~22G of space. 
 
Action Taken: 
Deleted all backup log directories older than 30 days  
 
 
Result: 
/usr/sap usage dropped from 91% to 19% (5.5G used, 25G available).
