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.

File system	Supported by				Limitations

File system	Agents	WinPE bootable media	Linux-based bootable media	Mac bootable media	Limitations
FAT16/32	All agents	+	+	+	No limitations

ext2/ext3/ext4		+	+	-
HFS+	Agent for Mac	-	-	+
APFS	Agent for Mac	-	-	+	Supported starting with macOS High Sierra 10.13 Disk configuration should be re-created manually when recovering to a non-original machine or bare metal.
JFS	Agent for Linux	-	+	-	Files cannot be excluded from a disk backup Fast incremental/ differential backup cannot be enabled
ReiserFS3		-	+	-
ReiserFS4		-	+	-	Files cannot be excluded from a disk backup Fast incremental/ differential backup cannot be enabled Volumes cannot be resized during a recovery
ReFS	All agents	+	+	+
XFS	All agents	+	+	+
Linux swap	Agent for Linux	-	+	-	No limitations
exFAT	All agents	+	+ Bootable media cannot be used for recovery if the backup is stored on exFAT	+	Only disk/volume backup is supported Files cannot be excluded from a backup Individual files cannot be recovered from a backup

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.
