→ Applies to: SynetoOS 4.x

When deduplication is enabled in the guest operating system of a virtual machine, the file recovery system in SynetoOS 4 does not support granular file-level recovery.

In such cases, the cloning feature can still be used to recover the virtual machine, allowing access to the necessary data via manual extraction.

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Become Super User

sudo su

Step 3. Connect to SynetoOS Luna via SSH as admin

ssh admin@172.16.254.3

Step 4. Become Super User

sudo su

Step 5. Access to the following path

cd /mnt/virtual-disk-browser/files/

Step 6. Check the contents of the folder

ls -al

EXAMPLE OUTPUT

These folders contain the virtual machine files. To identify the relevant ones, you need to explore the contents of the folders and locate the desired files.

Step 7. Navigate to the relevant directory (replace <uuid_name> and <folder_name> with the correct information)

cd /mnt/virtual-disk-browser/files/<uuid_name>/<folder_name>

EXAMPLE

cd /mnt/virtual-disk-browser/files/0578782b-6af5-4f0f-a0fb-b414633cd3fe/Test

Step 8. Check tag 0x80000013  (replace <uuid_name> and <folder_name> with the correct information)

ls -al /mnt/virtual-disk-browser/files/<uuid_name>/<folder_name>

EXAMPLE OUTPUT

lrwxrwxrwx 1 root root     34 Apr 20  2023 test.htm -> unsupported reparse tag 0x80000013
lrwxrwxrwx 1 root root     34 Apr 20  2023 test1.htm -> unsupported reparse tag 0x80000013

 

The presence of the 0x80000013 tag indicates that the virtual machine hosting the file uses a deduplication system or special metadata structures known as reparse points. These are used to support various features such as symbolic links, mount points, data deduplication, OneDrive placeholders, and more.
