Limitations in JFLR feature
Before openeing a support case please check the following conditions:
Version 6.0 and above:
- FAT and REFS file systems are no longer supported.
- FS level compression is not supported.
- In Linux EXT file system, only file and folder names encoded as UTF-8 or 7-bit ASCII are supported.
- Non EXT Linux file systems are not supported.
- Links are not supported.
- JFS, XFS, ZFS, ReiserFS file systems are not supported.
- If the Windows virtual machine with files to be restored uses dynamic disks, files cannot be restored from these disks.
- You can only recover files or folders when an offsite backup is not running.
- Journal File Level Restore (JFLR) is not supported with the vSphere plugin.
Versions 4.5 - 5.5:
- JFLR could only support restoration of files from file systems that the ZVM supports. Which means JFLR cannot support mounting "RAW" disks
- You could only recover files or folders from Windows machines. You cannot recover files or folders from Linux machines
- If the Windows virtual machine with files to be restored uses dynamic disks, files could not be restored from these disks
- When the Zerto Virtual Manager was installed on a Hyper-V Generation 1 virtual machine, you could only mount disks for file level recovery from a Hyper-V generation 1 virtual machine
- When the Zerto Virtual Manager was installed on a Hyper-V Generation 2 virtual machine, you could mount disks for file level recovery from a Hyper-V generation 1 virtual machine and from all disks except for the boot disk (usually C:) from a Hyper-V generation 2 virtual machine
- JFLR could not support mounting Windows Server 2012 disk formats when the ZVM is on a lower version like Windows Server 2008R2, although it will work the other way around
- JFLR couldn't mount more than one GPT with the same ID. This can be caused by using the same OVF for all the replicated VMs
- JFLR couldn't support VI client session due to the fact that it uses the browser download function therefore must be used in a session that's using HTML5 client
- When a large number of disks are mounted, when they are unmounted, some of the disks remain mounted and this is not reflected in the user interface
- You could only recover files or folders when an offsite backup is not running
- To restore files from a protected virtual machine when Role Based Access Control (RBAC) permissions are set in the Zerto Cloud Manager, your user must had both the "Manage VPGs" and "View Only" privileges set
- JFLR couldn't mount disk of a machine that configured to use UEFI or Secure Boot
- JFLR couldn't mount disks larger than 2 terabytes (provisioned size).
