AOMEI sells Windows software for backups and disks. AOMEI Backupper copies a system, a disk, or selected files so a PC can be restored after a failure. AOMEI Partition Assistant resizes, merges, and otherwise changes partitions, and it can copy a disk onto another drive.
These are separate programs. A backup tool does not replace a partition tool, and a partition change can erase data if the wrong disk is selected. AOMEI’s site also lists business backup and phone-transfer utilities, each with its own license.
The product page states which Windows versions are supported and whether the license is for one PC or for a technician who works on many. A backup only helps if it was made before the disk failed, and if the rescue media was created while the PC still booted.
