|
||||
chmod +x multibackup
|
||||
cp /usr/local/src/tar-multibackup/multibackup.conf ~/.multibackup.conf
|
||||
Ein komfortables Bash-Skript zur schnellen SSH-Verbindung mit bekannten oder neuen Hosts.

||||
* `backup_destination` = Directory which is used to store the archives/backups
|
||||
* `folders_to_backup` = Array of folders to backup
|
||||
* `backup_retention` = Retention time how long we should keep the backups
|
||||
* `pre_commands` = Array of commands that are executed before the backup starts (stop specific service)

||||
* `post_commands` = Array of commands that are executed after the backup finished (start specific service)
|
||||
* `tar_options` = Additional tar Options
|
||||
## 📦 Features
|
||||
|
||||
### Environment configurations
|
||||
- Liest bekannte Hosts aus `~/.ssh/known_hosts`
|
||||
- Zeigt Liste als `host:port` (durchsuchbar)
|
||||
- Direkteingabe oder freie manuelle Eingabe möglich
|
||||
- **Parameter-Unterstützung:**
|
||||

#### Example configuration
|
||||
|
||||
In the example below you can find a `multibackup` configuration file to backup a productional [LiveConfig](http://www.liveconfig.com/) instance.
|
||||
|
||||
`vi ~/.multibackup.conf`
|
||||
|
||||
# Timestamp format, used in the backup target filename
|
||||
timestamp=$(date +%Y%m%d)
|
||||
|
||||
# Destination where you want to store your backups
|
||||
backup_destination="/var/backups"
|
||||
|
||||
# Folders to backup
|
||||
folders_to_backup=(
|
||||
"/etc"
|
||||
"/var/mail"
|
||||
"/var/www"
|
||||
"/var/lib/mysql"
|
||||
"/var/spool/cron"
|
||||
"/var/lib/liveconfig"
|
||||
)
|
||||
|
||||
# Files and folders that are excluded in the tar command
|
||||
tar_excludes=(
|
||||
"nginx-php-fcgi.sock"
|
||||
)
|
||||
|
||||
# Additional tar Options
|
||||
tar_options=()
|
||||
|
||||
# How long to you want to keep your backups (in days)
|
||||
backup_retention="+7"
|
||||
|
||||
# Commands that are executed before the backup started
|
||||
# (We have to make sure the liveconfig process is not running)
|
||||
# (otherwise the databases changes while we try to save it)
|
||||
pre_commands=(
|
||||
"service liveconfig stop"
|
||||
)
|
||||
|
||||
# Commands that are executed after the backup is completed
|
||||
# (To restart the liveconfig process again, once the backup is completed)
|
||||
post_commands=(
|
||||
"service liveconfig start"
|
||||
)
|
||||
|
||||
#### Cronjob setup
|
||||
|
||||
To make sure the backup is executed automatically and recurring, we're going to add a simple cronjob:
|
||||
|
||||
`vi /etc/cron.d/backup-liveconfig`
|
||||
|
||||
#
|
||||
# cronjob to backup LiveConfig, daily at 5:00 am
|
||||
#
|
||||
|
||||
0 5 * * * root /usr/local/bin/multibackup &>/dev/null
