AOMEI Centralized Backupper helps you to create and manage backups for your client computers within same LAN from server side.
A: Generally, if there are too many clients (such as 10 or 20 computers) backing up to the same NAS or Network share storage simultaneously, it may lead to backup speed slow due to bandwidth pressure within the same LAN.
Therefore, AOMEI Backupper Network allows you to set the suitable numbers of clients that can be backed up at the same time based on the LAN bandwidth and the storage server's capacity.
However, the feature only works for these clients on which you perform backup manually via the AOMEI Backupper Network console. If these clients are performing schedule backup, it will be invalid. So, the actual numbers of clients performing backup may be greater than the one you set.
And, for schedule backups, you can set a different time for each computer in the same task or you can set a different time for each group to run this task so it can resolve the backup speed problem indirectly.
A: AOMEI Centralized Backupper doesn’t support backing up dynamic disks with disk backup and you can back up dynamic volumes with partition backup.
A: Please reboot the AOMEI Centralized Backupper program on the server-side, select and double-click the client computer with changing disk/partition information under Computers-->Controlled Computer, and then click the Refresh button to update.
A: If the client was online but becomes offline for some reason, it might be that the "Backupper Service" of the client has stopped. Please start the Windows Task Manager, select Services, and then restart "Backupper Service".
And, you can try to change the value CLEAN_VIRTUAL_ADAPTER from 1 to 0 under the path AOMEIBr\net\Global.ini on the server machine.
Also, you can try to set the property of AOMEI Backupper Server to "Delay Start" under Windows Task Manager.
If the problem remains, please contact our AOMEI Support Team and attach the log folder under the installation directories of AOMEI Centralized Backupper and the Agent so we will further analyze and help you find solutions.
A: Please first make sure your server and client are under the same physical LAN and manually install the Agent program on your client machines. We also advise you to close the anti-virus program and firewall and then check again.
And, please perform a two-way ping test first. If the ping can pass, please enable IP segment management and add the IP segment where the client machine is located in the AOMEI Centralized Backupper Settings and then refresh.
If the problem remains, please contact our AOMEI Support Team and attach the log folder under the installation directories of AOMEI Centralized Backupper and the Agent so we will further analyze and help you find solutions.
A: The network card might get a problem. Please check whether the network card of the current computer is enabled or the network environment is normal.
You can change the value "ABNET CLEAN_VIRTUAL_ADAPTER" value to "0" in the file "Global.ini" under the path C:\ProgaramData\AomeiBR\net and retry to load the program.
A: The problem might be caused if there is no environment to create WinPE on your client machines or the WinPE is downloaded unsuccessfully.
In this case, you can manually download WinPE here and then put the WinPE under the installation directory of AOMEI Centralized Backupper. And then, please retry to restore the image.
A: Please find and reload the PreInstall.exe file on the client machine under the path C:\Program Files (x86)\AOMEI Centralized Backupper\tools
After the PreInstall.exe is reloaded, please retry to remotely install the Agent on the client machine.
A: Please check if there is another AOMEI Centralized Backupper under the same LAN and the client machine has been occupied by another AOEMI Centralized Backupper. You can first cancel control on another server-side or the agent and request control again.
Or, we advise you to directly delete the Login file under the path C:\ProgramData\AomeiBR\net (on the client machine).
A: Please make sure your client machine is with an administrator account and has administrator permissions.
If the problem remains, please try to restart the AOMEI Backupper Service under Windows Task Manager and then retry.
A: You can match the label of these partitions with no drive letters to back up. But, AOMEI Centralized Backupper currently can’t back up partitions with no drive letters and volume labels. In this situation, you can run AOMEI Partition Assistant on clients to assign drive letters or volume labels for these partitions manually.
A: It might be that the username and password of the Share/NAS you added have changed. Please make sure both your server and client machines can access the NAS successfully and have enough permissions.
And, you can try to delete the NAS.xml file under the path C:\ProgramData and then re-configure the NAS path. Or, please click "new task" and then modify the username and password in the "Share/NAS device" panel under "Step 3: Select the destination location to save the backup". After that, back up again. Please noted that there is no need to create a new task, you just need to modify the username and password in Step 3.
A: You may confirm the cause with following guide.
1) Please check if you are using the account under Administrators and the password should be not null. And, please right-click "This PC"-->Manage-->Local Users and Groups to confirm the administrator account un-checks the "account is disabled" option.
2) There is no enough access permission for the clients' computers, Windows service of clients is closed or prevention software are running on clients (for example, firewall and antivirus program are running, UAC remote is disabled and etc). Please modify these settings on clients: you can copy from “C:\Program Files (x86)\AOMEI Centralized Backupper\tools\PreInstall.exe” on the server-side to clients and then run it, close anti-virus programs and personal firewall and so on. After that, please try to remotely install/ update again.
3) Please confirm if your client account has write/read permission for installation location when doing the remote installation.
4) If AOMEI Centralized Backupper is installed on Windows XP/Server 2003 system and the clients are running Windows 10, then you need to enable "SMB1.0/CIFS File Sharing Support" on your clients because of Windows XP/Server 2003 useSMB1.0/CIFS protocol. Please check the "SMB1.0/CIFS File Sharing Support" option and you can find it under Control Panel-->Programs and Features-->Turn Windows features on or off. And, please press "Win+R" to open the Run box, run "gpedit.msc" to open local Group, and then Enable insecure guest logons under Administrative Templates-->Network-->Lanman Workstation. And then, reboot client computers.
Note: You need to temporarily enable SMB 1.0 / CIFS File Sharing Support". After installation is completed, we suggest you turn off the "SMB 1.0 / CIFS File Sharing Support" for the sake of system security.
For any questions and problems, please feel free to contact AOMEI Support Team for further assistance.
