Systash

N|Systash

Backup solution for distributed compute platforms.

  • Ansible
  • Rust
  • Magic, just a little

Distributed Backups

Systash looks to solve an important task facing current and future deployed cloud infrastructure, which is data protection. Just as we rely on journal operations on our filesystem to provide data security, there should be that same effort taken for deployed systems through the use of system imaging and continuos backups.

Tech

Systash uses a number of open source projects to work properly:

  • [Ansible] - software provisioning, configuration management, and application-deployment tool.
  • [Rust] - fast memory safe programming language.

Installation

Install:

$ git clone https://github.com/Toure/Systash.git
$ cd Systash
$ cargo build --relase
$ cargo install

Edit the configuration file: (with your favortie editor)

Example Content [systash.conf]:

[Server]
host = "undercloud"
ip = "192.168.0.1"
system_group = "FO_North_01"

[[client]]
#client list defined here.

[client.node1]
host = "controller_0"
ip = "192.168.2.20"
system_group = "FO_North_01"

[client.node2]
host = "controller_1"
ip = "192.168.2.21"
system_group = "FO_Noth_02"

[backup_path]
# default path is root, this can be adjusted to include
# specific paths.
# base_dir = "/"
#
[exclude_path]
# ignore a specific set of paths.
exclude_dir = "
[storage]
archives = "/foo/storage"

[nfs_server]
host = "central_store"
ip = "192.168.2.254"

**nfs_server ip should correspond with the network which is addressable by the controller nodes.

Install packages on all nodes:

$ systash --install

Configure NFS Server on defined server node:

$ systash --init storage --profile server

Configure NFS Clients:

$ systash --init storage --profile client

Perform the first systems backup:

$ systash --backup

Generate a rescue image:

$ systash --rescue
