Best practice Backup Storage /Restore iSCSI/NFS

Hi

I have a question about the best practice to store Backup files.

This is my environment:
1x ESXi VMware Host 5.5
1x Acronis Backup for VMware Appliance
1x QNAP NAS with iSCSI/NFS Datastore in ESXi

I would like to use iSCSI/NFS Datastore with is connected to the ESXi Host but my question is "How can i restore a VM from Backup Files which are saved in a VMDK File on the Datastore (Acronis Local Storage Option with connected VMDK)?"

Is there a way to save Backup Files direct on the iSCSI/NFS Datastore which is connected to the ESXi Host? If the host failed and Needs to restore with BMR i can connect with the Acronis Bootable Media directly to the iSCSI Storage but how can i open the Backup files which are saved in the VMDK file? Can i Mount the VMDK and restore the ESXi Host? Same for NFS. I can browse to the VMDK File on the NFS Share but how can i open the File and restore the host data from Backup?

Would it be better to store the Backup Files not in a VMDK file and instead on an NFS Share in the Network (like \\nas-xxxx\Share)?

Kind regards

OK i found it. The keyword is "RDM" (RDM mapped iSCSI Storage).

OK, next Problem. I created the RDM iSCSI Storage for the appliance and i saved some backup files into the volume. I see the files in the WebGUI and the System automatically recognize my backups again.

Now i want to test the ESXi Host Restore Function of the Acronis Bootable Media for VMware. After starting from the CD i chose to connect to the iSCSI Storage stored LUN which is configured as RDM device. After the Connection has been established i see the LUN but i cannot connect to it. Other connections to iSCSI LUNs on the same Storage did also not work. Can someone tell me what to do?

For Details about the Error, see Attachement.

Kind regards

Hi Rico,

The functionality which recovers VMs automatically after restoring ESXi host configuration supports VM backups location only on SMB or (s)FTP shares. It's not possible to perform this recovery in automated way if you store your VM backups on iSCSI. In this case you should 1) restore ESXi configuration _without_ specifying the path to backups of VMs 2) deploy appliance to the restored ESXi host 3) attach your iSCSI storage to appliance (just like you did originally when backing up VMs onto it) and 4) Run VMs recovery.

Thank you.

Hi Vasily

I think you do not understand what i mean. The Function to recover a VM with Acronis Appliance is clear for me but the process to restore a ESXi Host Konfiguration after a ESXi Host fail is not clear for me.

I did the following steps:

1. Created iSCSI Storage an mapped LUN on QNAP an connect the iSCSI Device to the ESXi Host
2. Created a RDM Harddrive in the Acronis Appliance config which connects to the iSCSI LUN
3. Created local Storage in Acronis Appliance
4. Perform Backup Jobs to save both VM Backups and ESXi Host Configuration Backups on the local Storage (RDM)

The way to restore VM Backups is clear for me. I had to perform restore Task with the Appliance.

But i would like to Test the restore of a ESXi Configuration Backup?

I think the steps are These:

1. Create Bootable Acronis for VMware Media
2. Boot ESXi Host from the Media
3. Attach the iSCSI Device from QNAP
4. Map the LUN which contains the ESXi Host Configuration Backup Data
5. Perform a restore from the Backup

I hang on step 4. I can connect with the Bootable Media integrated iSCSI Connector to my NAS and i see the LUN but Connection failes with the error which i submited in the previous post.

Kind regards

Hi Rico,

The 4th step in your description is not correct one - you should save the ESXi host configuration backup to another location - it should be accessible from the bootable media environment (which you get when booting the new machine where you restore ESXi to) on either network share (SMB) or FTP storage. In other words you may keep your VM backups on that iSCSI device mapped as locally attached storage, but ESXi host configuration backups must be saved somewhere else (or copied). Thus you will be able to perform the ESXi recovery in 2 steps: 1) restore from ESXi host configuration backup from network share (or FTP) and 2) deploy appliance to restored host, reconnect iSCSI device as locally attached storage to this new appliance and perform VMs recovery.

Thank you.

Hi Vasily

Thanks for your reply.

But for what reason can i connect from the Acronis Bootable Media to a iSCSI Target when i am not able to mount a LUN from that? Is that a mistake that the Option is displayed????

See Attachment!

Kind regards
Rico

Hi Rico,

In fact you're right - this iSCSI attach option should not be displayed in bootable media environment. It was left from Acronis Backup edition for physical machines and was used to recover backups onto iSCSI targets without having to boot into Windows. Since there is no disk/partition recovery functionality in bootable media of Acronis Backup for VMware - this option doesn't make sense any more and should not be used. I have reported this problem to our developers, so that they can remove the button to avoid confusion.

Thank you.

Hi Vasily

Thanks for the clarification.

So now it is clear for me. I will use iSCSI RDM as local Storage for VM Backups and SMB or FTP Storage for my ESXi Configuration Backup Data.

best regards
