12.5 backup vm 2hosts 6.5
hi, i have a vcenter 6.5 U1 last release with 2 hosts connected
in the first host i have 3 vm windows 2012 420gb+400gb+100gb
in the second host i have the vcenter VM and the acronis 12.5 U2 build 9010 VM
every night acronis do a full backup of all 3 VM but it takes about 5 hours, if i move the acronis VM in the first host the backup is more faster, why?
hi, thanks for the reply, i'm just looking for disable nbdssl and back to nbd, the ssl version of nbd is the cause for slow backup performance
Hi,
To disable particular VDDK transport on appliance, you'll need to modify the /etc/Acronis/VirtualWare.config file on it:
1) Follow the instructions on how to connect to appliance via WinSCP utility: https://kb.acronis.com/content/60904 (in the bottom of the article)
2) Modify the /etc/Acronis/VirtualWare.config file in WinSCP text editor (F4)
3) In the "DisabledTransport" value add a list of disabled transports separated by ":" . List of possible values: "hotadd:san:nbd:nbdssl:file"
4) Save the modified file and reboot the appliance.
In case you use Agent for VMware (Windows) the list of disabled transports is controlled from HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\VirtualWare\VMwareESXServer\VixDiskLib\DisabledTransport Windows registry key, where "DisabledTransport" is a string value which contains a list of transports separated by ":"("hotadd:san:nbd:nbdssl:file"). Restart Acronis Managed Machine service to apply the changes.
Thank you.
hi, this change made no effect for my backup, is possible to use nbd and no nbdssl with vmware 6.5 U1 and acronis 12.5?
Hi,
The selected VDDK transport is shown in the backup log file for each virtual disk opened for read access. Note that the virtual disks are always first opened using NBDSSL transport for a very short period of time in order to read metadata information. The real data transfer starts after the disks are re-opened using the best available transport. Therefore in the log file you may see the following line first:
2018-04-17T05:18:37:832-07:00 6392 I00530000: Disk '[datastore1] SmallLinux/SmallLinux.vmdk' is opened with the following parameters - Read only: '1'; transport: 'nbdssl'; flags: '20'.
This is normal since the same disk will be re-opened further in the log using "hotadd" or other desired transport method (limited by configuring of "DisabledTransport" parameter).
If the above is not what you see in your case, please contact our support team for assistance with proper configuration of the parameter.
Thank you.
hi, where can i see the backup log to see The selected VDDK transport?
The easiest way to check all the logs is to go to Devices list->select backed up VM->click on Activity tab->click "Collect system information" link. In the generated .zip report check the \ServiceProcess\ folder which will contain text files - one for each backup attempt. An alternative way is to check mms.0.log from \BackupAndRecovery\MMS\ folder - it will list all activities performed by the backup agent.
Thank you.
