Incrimental Backup Question

Hello forum members,

If I have one main (full) backup image and one incrimental backup image, does it matter which one of those images I choose to append another incrimental backup to?

Another question - If I run a restore using an older incrimental backup image, will my computer be restored to that point in time when I first made that partiticular incrimental backup image? In otherwords, if I accidently back up a virus, could I restore my computer from an earlier incrimental backup image to get rid of the virus?

Hello rrssss,

Thank you for choosing Acronis Disk Backup Software.

Incremental backup is based on the first full backup and on all previously made incremental backups. It contains only changes in drive image that have been made since the last incremental backup (or since the full backup if there is no one incremental yet). So you can choose the full backup as well as the incremental image. In the first case you can delete the old incremental backup, in the second case you should save all the incremental image.

Please let me know explain: if you have the full image (F) and incremental backups (I1, I2, I3, I4). In order to restore I4 you need to have all preceding backups – I3, I2, I1, F. In order to restore I2 you need to have only backups preceding I2 – I1 and F. You can restore your image archive from any incremental backup (I1, I2, I3 or I4).

Thank you.
