VM Backup using Avamar and doing File level restores

I am running Avamar 6.1.1-87 and have been able to run Image level backups for both MS Windows and Linux VM's. On the Windows side I have been able to do both Image level and File level restores with no issues. When I look to do File level restores on the Linux server I get the follwoing message: "Extended partitions are not supported". Does anyone know if you can do file level restores from a VM Image, or do we need to do normal client level backups???

FLR for Linux VMs is supported but has some very specific requirements and limitations. These are documented on page 77 of the Avamar 6.1 for VMware Guide. Here are some excerpts with the limitations that are generally most relevant to customers:

VMware Tools must be installed on the target virtual machine. For best results, ensure

that all virtual machines are running the latest available version of VMware Tools.

Older versions are known to cause failures when browsing during the file-level restore

operation.

The following virtual disk configurations are not supported:

• Unformatted disks

• Dynamic disks

• GUID Partition Table (GPT) disks

• Ext4 filesystems

• FAT16 filesystems

• FAT32 filesystems

• Extended partitions

• Virtual disk with more than one partition

• Two or more virtual disks mapped to single partition

• Encrypted partitions

• Compressed partitions

The following limitations apply to logical volumes managed by Logical Volume

Manager (LVM):

• One physical volume (.vmdk) must be mapped to exactly one logical volume

• Only ext2 and ext3 formatting is supported

I too, cannot do FLR on any of my Unix servers, so none of my are supported.

So I have set my unix vm's to backup once a week with a 3 week retention.

and backup the server as a client based backup every night.

this then allows me to re-make the vm if needed from a vm backup, and/or restore only parts from the client backup.

The issues has been corrected. What I did was to reboot the Proxy servers. This allows me to do one backup and have the ability to do image and File level restores.
