Either I don't understand something or TI isn't working. I have Acronis®*True*Image*Home® version 10.0 (build*4,871). Here's what I did: 1. Created Backup Location f:\David with: Max backups=3 Max size = 100 gb Storage period limit=20 2. I create a scheduled task of to backup up a single folder, c:\BackupTEst which has a single file in it, Test.Txt. I set this to use differential backups. 3. I edit Test.txt so it contains one character, "1" 4. I manually run the above task and it creates a tib file 5. I edit Test.txt so it contains 2 lines: 1 2 6. I manually run the above task again and it creates a new tib file 7. I edit Test.txt so it contains 3 lines: 1 2 3 8. I manually run the above task again and it creates a new tib file. There are now 3 ti files: 2006_11_10_22_56_59_487F.TIB 2006_11_10_22_56_59_487F2.TIB 2006_11_10_22_56_59_487F3.TIB 9. I do a restore to a new location, picking the 2nd file, ie, 2006_11_10_22_56_59_487F2.TIB 10. It does the restore but the contents of Test.txt are the same as after the 3rd iteration, that is, 1 2 3 I expected to see the contents after the 2nd iteration: 1 2 In fact, even if I pick the 1st file, I see the contents after the 3rd iteration. Am I wrong or is TI?
