ServerBackup

Server backup to cloud

It can rotate the bucket which is backup destination of each day.

Prerequisites

Any sync tool

For example,

• s3sync (easy to use https://github.com/tilfin/s3sync forked from aproxacs/s3sync)
• gsutil (https://cloud.google.com/storage/docs/gsutil)

Setup

$ sudo -i
# mkdir -p /backup/log
# mkdir /backup/tmp
# cd /backup
# git clone --depth 1  https://github.com/tilfin/serverbackup.git
# cd serverbackup
# cp backup.conf.sample backup.conf

Quick Settings for Google Cloud Storage

Install gsutil

# apt-get install python-dev python-crypto
# cd /backup
# wget https://storage.googleapis.com/pub/gsutil.tar.gz
# tar zxf gsutil.tar.gz

Setup gsutil authentication

# /backup/gsutil/gsutil config -o /backup/serverbackup/boto.cfg

The above method is that the token refresh does not work. It is permanently set up in the following way.

1. Create a service account at your Google cloud console.
2. Select to furnish a new private key whose type is P12.
3. Put created .p12 file at /backup/serverbackup/<secret key file.p12>
4. Write /backup/serverbackup/boto.cfg with the content of the following

[Credentials]
gs_service_client_id = <service account email address>
gs_service_key_file = /backup/serverbackup/<secret key file.p12>
gs_service_key_file_password = <pass phrase for key file>

[Boto]
https_validate_certificates = True

[GSUtil]
content_language = en
default_api_version = 2
default_project_id = <Google Developer Project ID>

backup.conf

Edit following entries.

• Buckets
• Sync

Buckets=backup-bucket
Sync=/backup/serverbackup/sync.gsutil

Backup commands

bkcmd.d behaves like rcX.d. Kick each script with prefix 'S' in this directory. ${BKUP_PREFIX} is combined backup directory path and file prefix which is the day number (ex /backup/tmp/3-).

Crontab

Kick backup at 3:00am

0 3 *   *   *     /backup/serverbackup/backup

You can mail a backup result if you set MAILTO in crontab.
