# Introduction KVM domains are a great way to setup and structure your home IT services, one service per KVM domain. For example, you may want to host your own collaboration and file sharing platform or RSS feed aggregator server. If the number of home services keeps increasing, you may also want to manage lower level services, such as DNS, authentication and monitoring. In this situation, it is important to backup your domains with a sensible frequency (for example, weekly). `backvm` is a command line utility to copy KVM domains to a remote location for backup purposes. With a **KVM domain name** (or a list of domain names) in the local KVM hypervisor and a **target server and location** as input parameters, `backvm` creates a copy of all the virtual disks that are part of the domain and the domain XML definition at the chosen target location. With these files, you can restore your KVM domains in a new host, if a failure occurs in the live one. Below, you can see a basic call to the utility that would backup domains `dom1`, `dom2` and `dom3` to the server `myserver`: ``` $ backvm --dom-names dom1,dom2,dom3 --dest-server-conf backup_dest_conf.json ``` ``` $ cat backup_dest_conf.json { "_comment" : "Backup server configuration", "dest_server" : { "dest_hostname": "myserver", "dest_username": "myusername", "dest_folder": "/tmp/" } } ``` # Features * The backup can be applied both on active (using snapshots) and inactive domains. * The backup process report can be sent by email. * The utility supports dry-runs to avoid long waiting times during setup and test. * The backup log location can be customized. # Limitations * The utility supports only SSH key-based authentication to the target server. * The utility must run in the same host of the KVM hypervisor. # Installation The utility is built on `libvirt-python` that needs the header files and static libraries to develop applications with libvirt. These files are typically contained in a package. In Ubuntu 20.04, this is called `libvirt-dev`. Once `libvirt-dev` (or equivalent) is available on the system, you can install with: ``` pip install backvm ``` It is recommended to install in a virtual environment. # Usage ``` Usage: backvm [OPTIONS] This program performs the backup of one or several KVM domains Options: --email-conf TEXT The path of a json file that contains the email configuration. If specified, it must contain a root element called "email". This element must then contain the following values: - smtp_port - smtp_server - sender_email - from_email - sender_password - receiver_email --dest-server-conf TEXT The path of a json file that contains the server configuration. This is a required parameter. The json file must contain a root element called "dest_server". This element must then contain the following values: - dest_hostname - dest_username - dest_folder [required] --backend-copy-utility TEXT The backend copy utility to do the remote copy. Possible values are 'scp' and 'rsync' [default: rsync] --dom-names TEXT Comma-separated list of domain names [required] --do-backup TEXT Whether the backup operation is actually done. Useful when you are testing and you want to avoid long waiting times. Possible values 'True', 'False'. --do-archive TEXT This option will group all the files related to a domain in a single tar archive domname.tar. Possible values 'True', 'False'. --temp-folder TEXT Specify the folder where the process will write its temporary files. In case you specify --do- archive = True, take into account that the filesystem of this folder must have a size at least equal to the sum of the sizes of the disks of the larger domain you are backing up. There are no checks. [required] --logfile TEXT The location of the log file, by default /tmp/kvm_domains_backup.log [default: /tmp/kvm_domains_backup.log] --help Show this message and exit. ```
