I have AOMEI Backupper Standard Free edition. Icreated the initial System backup (SB) and I have Differential backups (DBs) scheduledto run and verified every Friday at 6pm. These Differential images are backedup to a second internal hard drive and then I copy these images to an external500GB hard drive via USB3.0 connection so I have two copies. I believe that torestore everything only the SB and the latest DB are required, unlike Incrementalbackups (IBs) which require all images to be used. I therefore keep theoriginal SB and manually delete all but the last two DBs. I believe thatmanually deleting previous IBs causes damage to the version chain causing the IBsto become invalid. My question is am I correct in that manually deleting previousDBs (not IBs) will not damage any version chain causing the DBs to become invalidand that I can be sure that the restore will work when needed?
