Configuring the backup jobs¶
The configuration of the backups is done in an .ini file,
by default /etc/tis/tisbackup-config.ini
:
a global section where general parameters are specified;
then for each backup a section will be created;
[global] section¶
Here are the mandatory parameters of the global section.
the beginning of the global section starts with:
[global]
specify directory where to store backups:
backup_base_dir = /backup/data/
define the maximum age of the backups (variable used by the cleanup function):
backup_retention_time=140
define the maximum time in hours between each backup. When this time is exceeded, then checknagios goes critical:
maximum_backup_age=30
Another non-mandatory parameter allows to define the rsync compression level:
compression_level=7
.
Backup types¶
Note
to test with a Windows box
Globally, the backups are done through an SSH connection and the steps are:
creating the section in the configuration file;
installing ssh on the Linux client;
making an ssh key exchange between the tisbackup server and the client to back up;
Here are the different types of backup possible with tisbackup.
Backing up a MySQL database¶
[srvintranet_mysql_mediawiki]
type=mysql+ssh
server_name=srvintranet
private_key=/root/.ssh/id_dsa
db_name=mediawiki
db_user=user
db_passwd=password
Mandatory parameters:
[srvintranet_mysql_mediawiki]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;server_name
: defines the server to be backed up by its DNS name or IP address;private_key
: defines the name of the private key to be used to connect to the client;db_name
: defines the name of the database to dump;db_user
: defines the name of a user with the right to dump on the basis of;db_passwd
: defines the user’s password;
Backing up a PostgreSQL database¶
[srvasterisk-pgsql]
type=pgsql+ssh
server_name=srvasterisk
private_key=/root/.ssh/id_rsa
db_name=asterisk
Mandatory parameters:
[srvasterisk-pgsql]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;server_name
: defines the server to be backed up by its DNS name or IP address;private_key
: defines the name of the private key to be used to connect to the client;db_name
: defines the name of the database to dump;
Backing up a file server¶
[srvfiles-home]
type=rsync+ssh
server_name=srvfiles
remote_dir=/home
private_key=/root/.ssh/id_dsa
exclude_list=".mozilla",".thunderbird",".x2go","*.avi"
bwlimit = 100
Mandatory parameters:
[srvfiles-home]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;server_name
: defines the server to be backed up by its DNS name or IP address;remote_dir
: defines the folder on the remote host to backup;private_key
: defines the name of the private key to be used to connect to the client;Attention
In case of Windows client, specificities are to be expected:
By default we use the root user for backups, for windows we will use the Administrator account (pay attention to the sensitive box).
remote_user=Administrator
Through cygwin, the directory to be backed up will always start with
/cygdrive
, so it must be specified in theremote_dir
parameter.remote_dir=/cygdrive/c/WINDOWS/
Hint
Other non-mandatory parameters can be used. The listdrivers
option
allows you to see them. The two most frequently used parameters are:
exclude_list
: defines the files to be excluded from the backup;bwlimit
: defines the maximum speed of the backup;
Backing up a XenCenter virtual machine¶
On local storage¶
[wsmanage]
type=xen-xva
xcphost=srvxen1
server_name=wsmanage
password_file=/root/xen_passwd
backup_retention_time=2
halt_vm=True
enable_https=False
Mandatory parameters:
[wsmanage]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;xcphost
: defines the XCP server where the VM is found by its DNS name or IP;server_name
: defines the server to be backed up by its DNS name or IP address;password_file
: defines a file where are stored the user and the password to be used for exporting the .xva file;backup_retention_time
: defines the maximum number of exports for the virtual machine;halt_vm
: True = stop the virtual machine then export, False = snapshot the virtual machine then export thexva
without stopping the virtual machine;enable_https
: activate or deactivate https protocol for transfer;
On remote storage¶
[srvads-copy]
type=copy-vm-xcp
server_name=srvxen1
vm_name=srvads
storage_name=iscsi-sr1
password_file=/root/xen_passwd
network_name=test-dcardon
max_copies=3
Mandatory parameters:
[srvads-copy]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;server_name
: defines the server to be backed up by its DNS name or IP address;vm_name
: defines the virtual machine to be backed up (its name-label in XCP);storage_name
: defines the storage to where to copy the virtual machine (its name-label in XCP);password_file
: defines a file where are stored the user and the password to be used for exporting the .xva file;network_name
: defines the network to which to copy the VM (its name-label in XCP);max_copies
: maximum number of exports for the virtual machine;
XenCenter metadata¶
[srvxen1-metadata] type=xcp-dump-metadata server_name=srvxen1 password_file=/root/xen_passwd
Mandatory parameters:
[srvxen1-metadata]
: name of the section starts with the name you give to it;type
: specifies the backup type for the Mysql database dump;server_name
: defines the server to be backed up by its DNS name or IP address;password_file
: defines a file where are stored the user and the password to be used for exporting the .xva file;
Attention
For maximum security put the password file in the root directory with read-write access only for it.
vi /root/xen_passwd
example of the content of the file:
user
password
implementation of restricted rights
chmod 600 /root/xen_passwd
