=== Description ===
=== Description ===
This contrib uses dar (http://dar.linux.free.fr) to create a feature rich backup system for smeserver 7.x to network shares or attached USB disk. Based on and supercedes smeserver-backup2.
This contrib uses dar (http://dar.linux.free.fr) to create a feature rich backup system for smeserver 7.x. It adds a server-manager panel (Backup > Disk ARchive) to define, schedule and launch server backups and restores, including full disaster recovery, to and from network shares or an attached local disk. The destination network share can be any accessible network mapped drive. Another server, pc workstation or network attached hard drive. The destination local disk can be any mountable hard disk. IDE/SCSI/SATA/USB. In addition an unlimited number of custom backups may be scheduled.

==== Midnight Commander (MC) dar-extension ====
With the installation of DAR2 comes an extension for viewing .dar files from within Midnight Commander but it is not installed by default. You can find the files extracted in the /opt/dar2-mc directory. For installation of this extension run the install.sh shell script with:
cd /opt/dar2-mc
./install.sh
==== DAR2 command line scripts ====
Located in /etc/e-smith/events/actions/
dar2-backup = script that performs backup<br>
dar2-dr-restore = script that performs a complete disaster recovery restore<br>
dar2-mc = script that launches Midnight Commander and provides access to your archives<br>
dar2-restore = script that performs restore<br>
==== Manual restore of DAR2 configuration ====
It is possible to selectively restore the DAR2 configuration (backup job settings etc) from a full system backup.
Firstly install the DAR2 contrib on a new server, which will of course have no backup jobs configured.
Then look at the backup file in the backup target location and find a file called db.zip. Extract the dar2 db file and copy it to /home/e-smith/db on the new server, to restore the previous DAR2 configuration.
===Known issue===
====Cifs Error====
When using the included backup functionality, or the DAR2 contrib, backing up to a windows remote share generates the following cifs errors. see [[bugzilla:7341]]
Feb 12 11:51:25 sme e-smith-bg: Connecting /mnt/dar2/backup to \\192.168.10.30\bkp
Feb 12 11:51:25 sme kernel: CIFS VFS: Send error in SessSetup = -12
Feb 12 11:51:25 sme kernel: CIFS VFS: cifs_mount failed w/return code = -12
Feb 12 11:51:25 sme e-smith-bg: mount error(12): Cannot allocate memory
Feb 12 11:51:25 sme e-smith-bg: Refer to the mount.cifs
The solution could be to modify the windows registry by the file below
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"LargeSystemCache"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters]
"Size"=dword:00000003
Save the content above in a file with the name W7-backup.reg and import it in the windows registry, restart the service or the Windows computer
