Do you ever though about creating a backup copy of your domains in GlassFish , for example before doing something unpredictable , meanwhile you like your domain because of its configurations ?
here is simple steps to create backup and restore those backup.
before we go any further you should know , domaindir that we see in many of asadmin commands has a default value its default value is : GlassFish_home/domains , in all of those commands that has domaindir parameter, if you explicitly do not identify the domaindir asadmin will use the default values. So , when you use domain1 in some command , asadmin will look inside GlassFish_home/domains for that particular domain. steps to create a backup :
- Execute asadmin from bin directory under GlassFish_home
in case that you want to create a backup from a domain named domain1 (which is default domain)
- execute : backup-domain –description "I made this backup before changing default domain descriptor" domain1
after you execute this command , asadmin will create a folder named backups inside GlassFish_home/domains/domain1 and place a zip file there. The zip file is a backup of your domain . For example the zip file could be : sjsas_backup_v00001.zip it means that it is first backup that you create for this domain.
if you open the zip file you can see a file named backup.properties which contain informations like :
#Wed Apr 26 01:00:40 IRDT 2006
timestamp.human=Wed Apr 26 01:00:40 IRDT 2006
description=I made this backup before chaning default domain descriptor
There is a command which helps you to find out how much backups you have and shows you information related to each backup entry you made.This command is : list-backups it get an operand , the operand will be your domain name. You can also tell it that your domain dir is not the default place using –domaindir parameter.
Now lets see how we can restore this backup using asadmin administration console.
there is a command named restore-domain , this command will restore a domain using a backup file. Simply you need just to pass an operand which is your domain name. If you do this , it will restore your domain using your latest backup .
So if I execute : restore-domain domain1 it will looks inside the backups folder (the default place) and select latest backup then it will try to restore the domain using that backup.
you can use –filename parameter to specify another backup file which should be passed using a full path.
I should say that this command accept domaindir parameter as other commands that we talked about them this time.
