how do we know whether xml backup is recommended for a setup during migration. till how much gb data does xml backup support during server migration
Hello, Padmasree.
If I understood your question correctly, the answer is that there's no limit size on the XML Backup. The only issue is that the larger the backup the more time it will take to import all the data, I've seen XML Backups up to 3~4 GB and it takes many hours to complete an import.
Depending on the situation, you can create the backup using a database, like pg_dump or mysqldump, as that could be faster.
Kind regards,Maurício Karas
Yes, you can use XML backup and there is no limitation. But let me share my experience.
Our confluence instance is quite large instance and XML backup is around 4-5GB. But when I import it back again process has been hanged. However after few weeks I noticed that issue has been occurred due to third party add-on.
So before try this this in production instance, try to export/import XML backup in staging instance.
Hi Mauricio Karas,
when we switch the db's we have xml backup as the only option. so I thought of checking the limitations. if db size is 1gb , will xml backup be larger than the db size.
Hi Heshan,
have you tried switching the db's using xml backup, as we are trying to change the db from MySQL to postgresql
Then you have to use XML backup feature or any other tool. Best thing is try in a staging instance and verify before and after;
Also make sure to use server which has enough CPU and memory. Otherwise your XML import may hang.
will xml back up work on same version of Jira/confluence or can we use the xml backup in a upgraded version of Jira or confluence. eg can use xml backup of Jira version 6 in Jira version 7
