Selecting Disks And Volumes; Selecting Files And Folders - ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual

6.2.4.1

Selecting disks and volumes

To specify disks/volumes to back up
1. Select the check boxes for the disks and/or volumes to back up. You can select a random set of
disks and volumes.
If your operating system and its loader reside on different volumes, always include both volumes in the
backup. The volumes must also be recovered together; otherwise there is a high risk that the operating
system will not start.
In Linux, logical volumes and MD devices are shown under Dynamic and GPT. For more
information about backing up such volumes and devices, see "Backing up LVM volumes and MD
devices (Linux) (p. 32)".
2. [Optional] To create an exact copy of a disk or volume on a physical level, select the Back up
sector-by-sector check box. The resulting backup will be equal in size to the disk being backed up
(if the Compression level option is set to None). Use the sector-by-sector backup for backing up
drives with unrecognized or unsupported file systems and other proprietary data formats.
3. Click OK.
What does a disk or volume backup store?
For supported file systems, with the sector-by-sector option turned off, a disk or volume backup
stores only those sectors that contain data. This reduces the resulting backup size and speeds up the
backup and recovery operations.
Windows
The swap file (pagefile.sys) and the file that keeps the RAM content when the machine goes into
hibernation (hiberfil.sys) are not backed up. After recovery, the files will be re-created in the
appropriate place with the zero size.
A volume backup stores all other files and folders of the selected volume independent of their
attributes (including hidden and system files), the boot record, the file allocation table (FAT) if it
exists, the root and the zero track of the hard disk with the master boot record (MBR). The boot
code of GPT volumes is not backed up.
A disk backup stores all volumes of the selected disk (including hidden volumes such as the
vendor's maintenance partitions) and the zero track with the master boot record.
Linux
A volume backup stores all files and folders of the selected volume independent of their
attributes, a boot record and the file system super block.
A disk backup stores all disk volumes as well as the zero track with the master boot record.
6.2.4.2

Selecting files and folders

To select files and/or folders for backing up
1. Expand the local folders tree items in order to view its nested folders and files.
2. Select an item by checking the corresponding check box in the tree. Selecting a check box for a
folder means that all its content (files and folders) will be backed up. That is also the case for new
files that will appear there in the future.
A file-based backup is not sufficient for recovery of the operating system. In order to recover your operating
system, you have to perform a disk backup.
