OneKey System Backup
Case 1. You can't choose partition to store system image
Q: How can I know if partition can create recovery partition or not? (Free Space
Insufficient)
A: AOMEI OneKey will first check your system disk automatically
to look for a partition which has enough free space to create recovery partition. If there isn't
any partitions meeting the needs, the next step will be unavailable. In this case you may remove
some useless files to free up enough free space.
Q: If unallocated space is not large enough? (Unallocated space
insufficient)
A: The selected unallocated space isn't large enough, so the
program cannot use it for creating Recovery Partition. There are two solutions to recommend to
you: First, you use AOMEI Partition Assistant to
resize the partition or remove useless file to make an available unallocated space for creating
Recovery Partition; second, you can choose "Backup system to other location"
Q: Can I backup system to external hard drive?
A: If there is no enough
space in computer partition except for external hard drive, only way of backup you can choose is
to backup system to other location. You can choose external hard disk as the place where to
store system image file. Of course, computer will also create a AOMEI OneKey Recovery Partition,
which is stored recovery environment, but it don't need much more space than directly backup
system to OneKey Recovery Partition.
Q: There are some partitions with adequate free space, why can't I choose it?
(Inappropriate Partition Layout)
A: AOMEI OneKey cannot create backup when
there is a structure of "logical partition, primary partition, logical partition" one
after another, or even there will create such a structure when you use AOMEI OneKey. In this
case, please use AOMEI Partition Assistant to
covert the primary partition to logical and then retry or use AOMEI Backupper to
do the backup.
Q: My computer partition has huge space, but why can't I create recovery partition?
(Disks Greater Than 2TB)
A: It may be that your system disk is MBR type (please
check it for sure). MBR disk can’t be larger than 2tb even if the disk capacity is larger than
2tb. So, if you want to make the extra disk space available, just convert system disk
to GPT with AOMEI Partition Assistant, but make sure computer motherboard supports UEFI
boot mode. Then, OneKey Recovery can create recovery partition on system disk.
Q: Why is volume partition fail to be backed up?
A: If the system disk is a
dynamic disk, AOMEI OneKey is unable to back it up, in this case, please use AOMEI
Backupper to do a system backup. It's a-full-featured backup software. Or, use AOMEI Partition Assistant to convert the
dynamic to basic first, then, use OneKey to backup system partition.
Case 2. Failed to backup system
Q: There are three disks in my computer, why does only system disk show in the interface?
(Only create the recovery partition on a system disk)
A: There may be multiple
hard drives on your computer, and you could hope to make a recovery partition on secondary
disks, but currently AOMEI OneKey only supports for create the recovery partition on a system
disk. If you choose "Backup system to other location", you can backup system image to
other disk, but Windows PE micro-system will be stored in system disk.
Q: My system disk's sector is not 512 byte, is it possible to backup system?
(Non-Standard Sector)
A: The sector size of your hard disk is not 512bytes per
sector. AOMEI OneKey doesn't support this kind of disks. It's called non-standard disk.
Q: How is recovery partition created? (Allocate Space from the Existing
Partition)
A: AOMEI OneKey can only divide the existing partition (NTFS or
FAT32 file system) for creating Recovery Partition. There must have at least a NTFS or FAT32
partition, at the meantime, it has enough free space, otherwise AOMEI OneKey cannot create
Recovery Partition. But it is often the case that you can allocate some free space from system
partition for creating Recovery Partition.
Q: I unplug USB flash drive during AOMEI OneKey enters Windows PE, but I don't backup
system, why does software post error? (Disk or Partition Counts Changed)
A:
AOMEI OneKey will automatically enter Windows PE mode to perform the backup. If the counts of
your disks or partitions changed during AOMEI OneKey enter Windows PE, the backup operation will
fail. So please keep the disk and partition counts as same as in Windows before it enter Windows
PE mode. If you encountered the issue, you can directly press the "A" key or use
Windows boot menu item to enter into AOMEI OneKey Windows PE mode to make a backup or restore
when your computer startups.
Q: How to avoid Possible BSOD:
A: It is known that resizing system partition
of Windows Server 2003/2008 may cause BSOD in a few circumstances due to the special computer
circumstance. So for Server 2003/2008 administrator, we suggest you'd better choose a
partition other than system partition for creating Recovery Partition or use AOMEI Partition Assistant to shrink the system
partition, and then run AOMEI OneKey. Of course, The BSOD does not affect data and also does not
affect normal boot of the system.
OneKey System Recovery
Case 1. Why doesn't "OneKey System Recovery " work
Q: There are two ways in the interface of recovery, but why can only one option be
available?
A: There are two ways to back up, of course, there are also two ways
to recover system. But, if you just back up system in one way, for example, you just choose
"Backup system to AOMEI OneKey Recovery partition" this way to back up system, the
only way to recover system is to use system image files in AOMEI OneKey Recovery partition to
restore system.
Q: Why I can't restore my system backup to MBR (Restoration of Different Disk
Styles)
A: It is not supported to restore a system backup based on GPT to MBR
disk or MBR to GPT disk.
Case 2. Accident during system is being recovered
Q: Can I use AOMEI OneKey Recovery to recover system backup created by AOMEI
Backupper?
A: AOMEI OneKey Recovery and AOMEI Backupper are
products designed by AOMEI Tech, though. Sometimes, in some condition, it will be not successful
that recover system image that created by AOMEI Backupper with AOMEI OneKey Recovery. Such as,
image file of data partition, image file of dynamic volume, image file in GPT disk.
Q: I stored system image in dynamic volume, why can't I recover system
image?
A: You'd better not backup your system to such devices: Dynamic
volume, Non-512Byte sector disk, Network sharing, or the storage device that needs to load
drivers and then can run normally. Because process of backup and recovery will be running in the
Windows PE model, and programs can't recognize such devices.
Case 3. Some accident after recovery
Q: Can I restore my system image to the partition that is right to recovery
partition?
A: If you use AOMEI OneKey to restore your system to the place on
the right side of Recovery Partition, after you reboot, the System Backup feature will be no
longer available. The reason is AOMEI OneKey will delete the previous Recovery Partition at the
next time when you are trying to renew the Recovery Partition, that may cause the system cannot
boot anymore, so for safety, you are forbidden to renew recovery partition. If you want relive
this limitation, please use AOMEI Partition
Assistant or Windows Disk Management to delete the Recovery Partition.
Q: After system image is recovered to other disk, the setting in AOMEI OneKey can't
be working? (why has the prompting words "press A to enter AOMEI OneKey Recovery"
gone)
A: After system image is recovered to other disk, instead of the disk
where former system partition is, and then boot computer from the destination disk, the setting
in AOMEI OneKey Recovery will not work. Because setting options have been set by program before
backup, but it is aiming to the disk where former system is. System booting from Destination
disk can read the setting option that was set before, though, the setting option can't work.
If you want use starting setting, you have to back up current system with AOMEI OneKey Recovery.
