I am new to VEB and have just started using it to backup a laptop. First backup was 72GB out of a 124 GB SSD drive (very reasonable), but second backup 24 hour later is 23 GB. Except for some light web browsing and some pst file updates no work was done on the laptop during this time. The OS files are only ~10GB total so it cannot be due to changes in Windows system files. As your incremental is based on blockl evel changes a few dozen emails added to pst files should explain it either.
Any idea why incrementals could be so large over such a short interval? The backup job is full system protection and the laptop has on one 120GB SSD drive, running Windows 10.
Is there a way to run a diff on backups to see what changed?
