Supported file systems

A backup agent can back up any file system that is accessible from the operating system where the agent is installed. For example, Agent for Windows can back up and recover an ext4 file system if the corresponding driver is installed in Windows.

The following table summarizes the file systems that can be backed up and recovered. The limitations apply to both the agents and bootable media.

No limitations

The software automatically switches to the sector-by-sector mode when backing up drives with unrecognized or unsupported file systems. A sector-by-sector backup is possible for any file system that:

  • is block-based
  • spans a single disk
  • has a standard MBR/GPT partitioning scheme

If the file system does not meet these requirements, the backup fails.
