I converted to QB Pro Desktop 2019 in October/November of 2018, ever since then about 80% of the time I do a backup (which is 2 to 3 times a week) it says there is a data discrepancy and I have to rebuild the data.  Different issues each time.  I am running off a SSD drive but have multiple other companies I run off the SSD drive with no issues.  Most issues, deal with old paychecks from many years ago (I am not using QBs payroll anymore) OR transaction counts being off.  Really irritating to rebuild constantly.  Any suggestions?
