Basic usage

Bahub is offering basic operations required to automate backup sending and receiving, not managing the server.

Sending a backup

$ bahub --config ~/.bahub.yaml backup some_local_dir
{'version': 72, 'file_id': 'E9D7103D-1789-475E-A3EE-9CF18F51ACA4', 'file_name': '2b2e269541backup.tar-v72.gz'}

Listing stored backups

$ bahub --config ~/.bahub.yaml list some_local_dir
    "v71": {
        "created": "2019-02-10 14:27:52.000000",
        "id": "1684C60D-28B0-4818-A3EC-1F0C47981592"
    "v72": {
        "created": "2019-02-11 07:54:52.000000",
        "id": "E9D7103D-1789-475E-A3EE-9CF18F51ACA4"

Restoring a backup

Restoring latest version:

$ bahub --config ~/.bahub.yaml restore some_local_dir latest
{"status": "OK"}

Restoring version by number:

$ bahub --config ~/.bahub.yaml restore some_local_dir v71
{"status": "OK"}

Restoring version by id:

$ bahub --config ~/.bahub.yaml restore some_local_dir 1684C60D-28B0-4818-A3EC-1F0C47981592
{"status": "OK"}

Recovery from disaster

In case you need to quickly recover whole server/environment from backup - there is a RECOVERY PLAN. A recovery plan is:

  • List of backups to restore (names from section “backups”)
  • Policy of recovery (eg. recover everything, or stop on failure)
# Recovery plans
#   Restores multiple backups in order, using single command
#   Possible values:
#     policy:
#       - restore-whats-possible: Ignore things that cannot be restored, restore what is posible
#       - stop-on-first-error: Restore until first error, then stay as it is
        policy: restore-whats-possible
        definitions: all

        policy: stop-on-first-error
            - local_command_output
$ bahub --config ~/.bahub.yaml recover default

Making a snapshot of multiple services at once

Snapshot works exactly in the same way as recovery from diaster, but it’s inverted. Instead of downloading a copy, it is actually uploading.

NOTICE: Be very careful, as this is a single command to backup everything, remember about the backups rotation

$ bahub --config ~/.bahub.yaml snapshot default
