We recently upgraded Solarwinds NPM 9.1 to 10.1.2 successfully 2 days back. I also took full DB Backup after upgradation. Today I again took full backup after doing some changes and it was showing me backup size from 10 GB (Last Backup) to 4 GB (Current). I start checking all and found that now the new defaul polling settings and maintenance settings changed and it deleted all the older data (60 days) after daily maintenance summerization.
I called Support number but they said it is MS SQL Server related issue and I should contact Microsoft support. for this.
Any help in getting the previous data along with these 2 days data will be highly appreciated.
