This section describes how the OpenVino servers are backed up using rsync:

 

Install rsync on all the servers:

[root@delta ~]# yum install rsync

alpha

 

root@alpha$ ssh-keygen -t rsa root@alpha$ scp .ssh/id_rsa.pub root@foxtrot:.ssh/authorized_keys_alpha root@foxtrot$ cat .ssh/authorized_keys_alpha >> .ssh/authorized_keys

 

Setup the crontab entry for root@alpha

 

0    3    *    *    *   rsync -avH --delete /home/mbarrow root@foxtrot:/backups/alpha 0    4    *    *    *   rsync -avH --delete /var/log root@foxtrot:/backups/alpha 10   5    *    *    *   rsync -avH --delete /var/www root@foxtrot:/backups/alpha 25   5    *    *    *   rsync -avH --delete /etc root@foxtrot:/backups/alpha

OpenBravo backup configurations

From the page http://wiki.openbravo.com/wiki/Installation/Appliance/Config#Synchronization_of_backups

 

To configure a backup policy follow these steps:

  1. Edit the configuration file for backups

  2. Set an schedule to perform the backups automatically

  3. Synchronize copies of backups on different servers

  4. Implement server redundancy.

Edit the configuration file to enable backups

Edit the file /etc/openbravo-backup.conf

 

# Enable or disable the backups ( yes / no ) BACKUP_ENABLED="yes" # Enable rotation of backups, this will mantain the number of backups specified and delete old ones ROTATION_ENABLED="yes" ROTATION_NUM_TO_MAINTAIN="40"

# This should be  <20GB of backups, and cover more than one monthly accounting period for Costaflores

# Enable the syncronization, this will run the specified plugins after a manual or auto backup # Add the plugins space separated. Example: SYNC_PLUGINS_TO_RUN="sync-s3 sync-label" # For custom sync scripts use: SYNC_PLUGINS_TO_RUN="/home/openbravo/backup-sync-methods/sync-custom" SYNC_ENABLED="no" SYNC_PLUGINS_TO_RUN="" # Config for sync-s3 plugin SYNC_S3_BUCKET="s3://BUCKET/openbravo-backups/" # Config for sync-label plugin SYNC_LABEL="backup-device" SYNC_LABEL_PATH="openbravo-backups" # Config for sync-samba plugin SAMBA_USER="" SAMBA_PASS="" SAMBA_HOST="" SAMBA_UUI="" SAMBA_SHARED_FOLDER="" SAMBA_SYNC_PATH="" ### ADVANCED OPTIONS ### # COMPRESSION OPTIONS # gz = quick and good compression # bz2 = better compression but slower # xz = very good compression but significatly slower # none = without compression, the quickest but no compression COMPRESSION_SOURCES="gz" COMPRESSION_DUMP="gz" ### ALTERNATIVE PATHS ### BACKUPS_DIR="/backups" BACKUPS_TMP_DIR="/tmp" ### EMAIL OPTIONS ### export EMAIL_FROM="somethingsomething@costaflores.com" export EMAIL_TO="info@costaflores.com" export EMAIL_SERVER="smtp.costaflores.com" export EMAIL_PORT="587" export EMAIL_TLS=True export EMAIL_USER="somethingsomething@costaflores.com" export EMAIL_PASSWORD="longpassword" export EMAIL_ENVIRONMENT="Openvino" export EMAIL_TEMP_FILE="/tmp/mailText.txt" export EMAIL_SUBJECT="Error en el Backup de Openbravo. Entorno: "$EMAIL_ENVIRONMENT ### COPY ATTACHMENTS ### export ATTACH_COPY="no"

Set an schedule to perform the backups automatically

 

Edit the openbravo crontab entry, to execute an automatic backup everyday at 08:00. Currently, the timezone set for bravo is CET, so the is equivalent to 03:00 or 04:00 in Argentina/Uruguay (depending on European summer time), and should be the least invasive time for this operation, though even if it was at 08:00 in South America, Mica Vera is not likely to be inputing data at that time.

 

# Openbravo backup # The backups cofiguration are in /etc/openbravo-backups.conf # Remove the comment mark '#' at the beggining of next line to enable the openbravo backups, put it back to disable the openbravo backups   0    8    *    *    *     /usr/share/openbravo/backup/backup-auto # ┬    ┬    ┬    ┬    ┬ # │    │    │    │    │ # │    │    │    │    │ # │    │    │    │    └───── day of week (0 - 7) (0 or 7 are Sunday, or use names) # │    │    │    └────────── month (1 - 12) # │    │    └─────────────── day of month (1 - 31) # │    └──────────────────── hour (0 - 23) # └───────────────────────── min (0 - 59)

 

Synchronize copies of backups on different servers

Having backups only on the local disk cannot safeguard against the worst problems. In case that this disk or the server breaks it is like not having any backups at all. By default OpenBravo includes methods for syncing with Amazon S3 and locally mounted storage (pen drives, secondary disks, etc.)

Rather than use either of these methods, we have opted to configure rsync to replicate the /backup directory to a secondary server

 

The essential command looks something like this:

rsync -avH --delete /backups/auto respaldo@

foxtrot:/backups/bravo

 

This command is executed on bravo as user "root" and will sync everything in the /backups/auto directory and system configuration directories to foxtrot:/backups/bravo

To setup this operation automatically, it is necessary to exchange pairs to eliminate the need to input the respaldo user password every time.

respaldo@bravo$ ssh-keygen -t rsa respaldo@bravo $ scp .ssh/id_rsa.pub root@foxtrot:.ssh/authorized_keys

 

At this point, user root should be able to ssh (and rsync) to foxtrot without having to provide a password.

Finally, we can create a crontab entry for user respaldo on bravo to rsync automatically, every day at 9am (CET) the directories to foxtrot:

 

0    9    *    *    *   rsync -avH --delete /backups/auto root@foxtrot:/backups/bravo 15    9    *    *    *   rsync -avH --delete /etc root@foxtrot:/backups/bravo 30    9    *    *    *   rsync -avH --delete /opt root@foxtrot:/backups/bravo 45    9    *    *    *   rsync -avH --delete /var/log root@foxtrot:/backups/bravo
