You can view all the partitions in the Disk Management app. Some drive partitions do not have a drive letter and these are not visible in File Explorer. You can view the hard disk partitions with a drive letter in File Explorer. You can create new partitions and delete the existing ones on your hard disk using Disk Management.

If needed, restore the backed up data to the backup source device with files/folders level.Disk Management is a utility in Windows 11 that lets you manage your hard disk(s).

Hence the existing folders and files will be deleted.

Run “mkfs.xfs –f –m crc=0 /dev/sdc1” if the backup source device is /dev/sdc1.ĬAUTION: This is a command to format /dev/sdc1.

If the existing data in the backup source device needs to be kept, backup all data.

If the device can be formatted, please perform the below steps. To disable CRC feature, the device has to be formatted and the existing data will be deleted.

Backup the device and verify the recovery point file size.

Note: e2fsprogs-1.43 or later needs to be installed in order to use -s option. If e2fsprogs-1.43 or later is manually installed on the system, please perform below steps as a workaround. To disable 64bit file system feature, e2fsprogs-1.43 or later is required but even Red Hat 7.4/7.5 or CentOS 7.4/7.5 does not implement e2fsprogs-1.43 yet. If your volume is less than 16TB, 64bit file system feature can be disabled. Please perform the below workaround in each file system in order to avoid backups for unused sectors. Without disabling CRC feature, System Recovery cannot get the recovery point file size as expected. Regarding XFS, Red Hat or CentOS enables Metadata cyclic redundancy checks (CRC) feature by default. Without disabling 64bit file system feature, System Recovery cannot get the recovery point file size as expected. Regarding EXT4, Red Hat or CentOS enables 64bit file system feature by default. This means that the size of the recovery point (v2i file) is much larger than expected.Īn example is a backup of an EXT4 partition that is 50GB in size with 3GB of used space produces a v2i file of 37GB.

Unused sectors are included in backups of EXT4 and XFS partitions on physical Linux servers (virtual machines are not affected).
