CNBS or CyberNet Backup
Server is a backup solution
designed to create selective
backups (online workstations
and servers) and, if necessary,
bare metal restore (offline
workstations and servers)
based on Linux, MS Windows,
OS X and BSD.

4. For the bare metal backup (hereinafter offline
backup) the specifications are as follows:
• Supports multiple filesystems and can
therefore be used to backup Linux, MS
Windows, Intel based Mac OS and FreeBSD,
NetBSD and OpenBSD, no matter if it is 32-bit
(x86) or 64-bit (x86-64) OS.
For these file systems, only used blocks are
saved and restored which increases the
efficiency. For any unsupported file system,
sector-to-sector copy is done.
• LVM2 and GRUB boot loader are supported.

5. What makes bare metal backup special?
• Almost all steps can be done via
commands and options.
• Multicast and massively clone are
supported if PXE boot and WOL are
enabled in your clients.
• The hostname, group, and SID of
cloned MS windows clients can be
automatically changed.
• The image file of the disk can be
recorded on local disk, SSH, Samba
or NFS server.

6. Limitations of the CNBS offline backup
procedure:
• The disk on which the deploy is done must be equal or larger than
the source image. Differential/incremental backup is not
implemented yet by the CNBS.
The partition to be cloned has to be unmounted at the moment of
cloning.
It is not possible to recover a single file from the image file, nor is it
possible to search it due to the way of compression. To recover a
single file from the backup, the image can be mounted on the
virtual machine using tools like virtual box or vmware player.
Network outages could corrupt the backup in progress.

7. For selective backup (hereinafter online
backup) the specifications are as follows:
Backup of the files in use (locked) at the moment of backup.
Selective choice of directories to be backed up.
Restoring single files from the backup archive without performing
the deploy of the whole backup.
Automation and scheduling of back up operations for each
workstation independently, as well as, keeping records and
reviews of all previous backup operations including the time of
the operation amount of data that is / will be backed up and the
next scheduled operation.
Domain environment is not required for the implementation of
the CNBS functioning, meaning it can operate in a workgroup.

8. Limitations of the CNBS online backup
procedure:
Administrator access privileges to
each workstation on which the
backup will be performed are
required either via domain admin
user or a local admin user.
Standard locations (like Desktop,
My Documents etc.) must be on
default locations if their backup is
planned, or we must be notified
to make the necessary changes.

9. Limitations of the current CNBS
online backup procedure:
The slightest change of any file that
has previously been backed up will
require a new backup of the whole
file, which decreases the efficiency
of the incremental backup…
As with the offline backup, a
functional, reliable and protected
network infrastructure is needed.
