Backup and Restore Procedures

I am trying to create backup and restore procedures for an Alfresco Community 5.1.0 system.After reading Alfresco documentation and forums I created the procedures listed below.I installed a new Alfresco system, created a new (non-admin) user and a new Site.I then followed these steps to backup and

Why is this marked as an "unpublished post"?

Our forums are receiving a large amount of spam everyday and your post was unfortunately flagged as a false-positive. I have deleted the duplicated topic that was also unpublished and published this post.

Sorry for the inconvenience.

I had the same problem and solved it using the information I gathered and customized. I backed up the entire alf_data directory in my process which is:

Alfresco-Community Cold Backup and Restore from a cold backup process

orginally posted by Francesco Corti in 2013

In the Alfresco wiki is described the backup and restore strategy but is not so clear how to do it in detail. In this post is shared a practical way to perform a restore of a backed up Alfresco in the way I like: a list of commands and tasks to execute… simpler to understand, to do and to test.

In this example is supposed that Alfresco-Community 201609 EA is installed in ‘/opt/alfresco-community’ folder and the DBMS used is PostgreSQL included with the installer. The restore strategy supposes that the backup is done as a “cold backup” described in this script:

#!/bin/bash

# Backup of Alfresco

# Written by Chris Newald – localized by Clint Davis Feb 2017

# Configuration:

CURRENT_FOLDER=$(pwd) # Script folder

TIMESTAMP=$( date +%Y%m%d%H%M%S ) # Create timestamp

DUMP_NUM=10 # Number of backups to keep

AL_FOLDER="/opt/alfresco-community" # Alfresco folder

AL_DATA="/opt/alfresco-community/alf_data" # Alfresco data folder

TARGET_FOLDER=”/backup” # Backup destination folder

DB_HOME="/opt/alfresco-community/postgresql" # PostgreSQL folder

# Function - Stop Alfresco

function al_stop()

{

$AL_FOLDER/alfresco.sh stop

# If Alfresco does not stop we MUST exit script

# Backing up files with Alfresco working may

# corrupt data indexes!!

if [ "$?" != "0" ]; then

echo "Alfresco Stop FAILED - STOP SCRIPT!"

exit 1

else

# Alfresco Stopped successfully

echo “Alfresco Stop successful!”

}

# Function - Start Alfresco

function al_start()

{

$AL_FOLDER/alfresco.sh start

}

# Function - Start Postgress SQL Server

function p_start()

{

$DB_HOME/scripts/ctl.sh start

}

# Verify that argument was provided

if [ -d "$1" ]; then

# A folder has been provided, save it

TARGET_FOLDER="$1"

else

# No argument was provided for backup location

echo "Usage: $0 [TARGET_PATH]"

exit 0

#----------------------------------------

# 1 - Begin by stopping Alfresco

#----------------------------------------

al_stop

#----------------------------------------

# 2 - Backup the Alfresco database

#----------------------------------------

# Start the postgress database (which is stopped automatically

# by the Alfresco stop script

p_start

# Create a filename for the database tar

DB_DUMP=alfresco_db_${TIMESTAMP}.tar

# Backup the database to the target folder

# -Ft = Export database as tar file

$DB_HOME/bin/pg_dump alfresco -U alfresco -h localhost -F t > $TARGET_FOLDER/$DB_DUMP

# Check if an error was returned

if [ "$?" = "0" ]; then

echo "DB EXPORT WORKED!"

else

echo "DB EXPORT FAILED!"

#------------------------------------------

# 3 - Backup the Alfresco content folder

#------------------------------------------

# Create a file name with timestamp

AL_DUMP=alfresco_data_${TIMESTAMP}.tgz

# Tar the Alfresco data folder to the backup

# to the backup folder specified

tar zcf $TARGET_FOLDER/$AL_DUMP $AL_DATA

echo "Alfresco Data folder tar complete"

#------------------------------------------

# 4 - Merge the database and data files

#------------------------------------------

# Create a backup filename with timestamp

BACKUP_FILE="alfresco_bak_${TIMESTAMP}.tgz"

tar zcf $TARGET_FOLDER/$BACKUP_FILE $TARGET_FOLDER/$AL_DUMP $TARGET_FOLDER/$DB_DUMP

echo "Database and Data File merge complete"

# If files were merged, delete the duplicates

if [ -f "$TARGET_FOLDER/$BACKUP_FILE" ]; then

echo "BACKUP SUCCESSFUL"

rm $TARGET_FOLDER/$AL_DUMP

rm $TARGET_FOLDER/$DB_DUMP

SUCCESS=1

#------------------------------------------

# 5 - We're done, start the Alfresco service

#------------------------------------------

al_start

#------------------------------------------

# 6 - Remove backups older than DUMP_NUM days

#------------------------------------------

if [ "$SUCCESS" = 1 ]; then

find $TARGET_FOLDER/*.tgz -type f -mtime +${DUMP_NUM} -exec rm {} \;

echo "Backups older than 10 days have been removed"

****************************************************************************************************************************************************************

NOW LET’S RESTORE FROM BACKUP FILES

The following Restore process and script was posted by Francesco Corti in 2013 and was localized by Clint Davis in February 2017.

First of all log in as root user.

1.) Find the backup merged db and data file named “alfresco_bak_yyyymmddtttttt.tgz” and copy it local to Alfresco server in /opt/alfresco-community/postgresql/temp/

2.) issue terminal command “tar –xvf alfresco_bak_yyyymmddtttttt.tgz” to extract the folder named ‘backup’ which contains your alfresco data and postgresql database backup files.

3.) Note the file names for use in the commands following.

Now Stop Alfresco-Community:

service alfresco stop

The DBMS runs using the ‘postgres’ user. Proceed with first task to restore the PostgreSQL database.

su – postgres

cd /opt/alfresco-community/postgresql/scripts

./ctl.sh start

cd /opt/alfresco-community/postgresql/bin

./psql (enter password for user 'postgres' when prompted)

DROP DATABASE alfresco;

CREATE DATABASE alfresco WITH OWNER alfresco;

Digit CTRL+d to exit from the shell.

./psql -U alfresco -d alfresco (enter password for user 'postgres' when prompted)

ALTER USER alfresco WITH PASSWORD 'alfresco password'; (use the admin password for user alfresco here)

Digit CTRL+d to exit from the shell. Supposing the DBMS backup is stored in the ‘alfresco_db_yyyymmddtttttt.tar’ file conforming to the backup strategy described above, let’s go ahead with the restoring of the database.

./pg_restore -d alfresco /opt/alfresco-community/postgresql/temp/backup/alfresco_db_yyyymmddtttttt.tar

(enter password for user 'postgres' when prompted)

exit

Now it’s time to restore the ‘alf_data’ folder with documents and indexes. Also in this case is supposed that the files are stored in a ‘alfresco_data_yyyymmddtttttt.tgz’ file conforming to the backup strategy described above.

cd /opt/alfresco-community

mv alf_data alf_data.old

cd /

tar zxvf /opt/alfresco-community/postgresql/temp/backup/alfresco_data_yyyymmddtttttt.tgz

That’s all!
Now it’s time to start again Alfresco and use it normally.

service alfresco start

I guys, noob here; just wondering: "Why aren't you using the cool script «BART» to manage backups"?

I've tried and it seems to work (backed up my alfresco install, made a fresh updated install, restored the data, everything seems to work quite well....)

Give it a try; you'll probably need to implement the restore part you are already wrote on your posts cause it's not yet implemented in the script, but it seems to manage quiet well all the backing up process...

This solution helps me with this task, but I needed alfresco backup and restore script but in the forum, I don't found a solution I decided to create this scripts and now this available on https://github.com/bruno-oliveira1 I hope yours enjoying.
