Using the ‘Multiple Mac Backup’ feature, you can backup data from multiple computers to a single IBackup for Mac account. It prevents data overlap in case you have files / folders with similar names, stored on multiple machines. On enabling this feature, your data is backed up to a folder with the same name as that of your computer. All future backups from this computer will take place inside this folder.
