Per our security breaks and guidelines when a database grow too big that it cant meet the requirements where it cannot be restored under a given RTO we need to plan on achieving same:-
Based on your experiences i would need some guidance and help here:-
Some insights on the database in question -
Total space --> Right click database-properties -> size = 10TB
What seems free in above --> Right click database-properties -> space Available = 5 TB
This database is an OLTP and critical one as it goes through lot of DUI operations throughout with heavy usage of TempDB
I have listed out TOP 10 tables with space and index usage:-
All top 5 as pulled are
partitionedtable with billion and million rows over 700 partitions in single table
Above tables have
Above tables have less than 3 indexes in most of them but compression at index level shows
For backup we do use compression with third party tool like idera to reduce size yet it crosses the threshold. Backup size is approx 1.9 TB for full backups. We do have diff and tran log backups as well.
I am little hesitant to go that shrinking route as it may impact performance but please help me with any ideas but else can be done to bring the space down?
Can we split few large table to their own separate database? If yes what is the catch?
Much appreciate all your help
