For details：[[en:use_case:how_to_perform_system_backup|How to perform asterCC system backup]]


===== Untar the Backup File =====

First，you should enter the directory of the backup files that download via "wget" command，then execute commands following：
<code>
 tar -xzvf astercc_files.tar.gz
</code>


===== Restore Database =====

==== Untar the Backup File of Database ====

After untar the backup file，we will untar the archive of database，we just need to execute commands following：
<code> gunzip -c astercc_db.sql.gz > astercc_db.sql </code>
If finished，you can find the database file named "astercc_db.sql".


==== Import the Backup File of Database ====

Import backup files into the database through commands following：
<code> mysql -u root -p astercc10 < XXXX.sql </code>
By the way，"astercc10" is the database name on the new server，"XXXX" is the file unzip from backup file of database，for example，here is "astercc_db"，So：
<code> mysql -u root -p astercc10 < astercc_db.sql </code>

At last，it prompts us to enter the secret of database.Under normal circumstances,the default secret is "astercc".Now，the importing of database is finished.We need modify 3 configurations of the new server manually which different from the old one：

1.In astercc.conf→[database]，such as：dbname、username、password
<code> vim /opt/asterisk/scripts/astercc/astercc.conf </code>

2.In astercc.conf→[statistics]，for example：dbname、dbpassword
<code> vim /opt/asterisk/scripts/astercc/astercc.conf </code>

3.At bottom of database.php，Under "class DATABASE_CONFIG -> default",for example：password、database
<code> vim /var/www/html/asterCC/app/config/database.php </code>



===== Restore Folder =====

Execute the following command one by one：
<code> \cp -rpf ./etc/* /etc </code>
<code> \cp -rpf ./opt/* /opt </code>
<code> \cp -rpf ./var/* /var </code>


===== Reload the Configure Files of System =====

After finished operations above，we should reloading the configure of system next. We just find "reloadconf.sh" in /opt/asterisk/scripts/astercc/ ,and execute it by "./"
<code> ./reloadconf.sh </code>


===== Solutions for Problems =====
After restoring astercc system，if you get "Permission denied!" after click the reload tip。You should execute command following:

<code> chmod 777 /var/www/html/asterCC/cake/console/cake </code>

After executing command,please restart asterccd，if it not worked,you can continue to execute commands following：
<code> chown -R asterisk.asterisk  /var/www/html/asterCC/
chown -R asterisk.asterisk /etc/asterisk 
</code>
