Migrating JIRA & Confluence from cloud to server size calculations

[Graeme Smith]

We are looking to move from our cloud implementations to the server editions and I've been tasked with collating the information needed to implement this move, specifically server disk space requirements for the databases. 

All I need to know is how to find out what the size requirements are for hosting the data from JIRA & Confluence.  Atlassian sent me a link to sizing requirements, but that was purely about how many processors and how much RAM, I need to find out what my database sizing will need to be.

Will be using MariaDB (nee MySQL) and we are a small operation (20 users).

• Backup zip for JIRA 1.1GB
• Backup zip for Confluence 657MB

Ended up throwing up a virtualbox for JIRA and Confluence evaluation and restored the data export to see what storage sizes were needed.

Then used the sizing guides in the documentation for the rest of the specification

Impossible to tell from the zip sizes, as we don't know what the proportions are.  Some places may have huge amounts of attachments which don't affect database sizing (e.g. 3,000 icon files and 3,000 high-res screenshots will take up hugely different amounts of disk space under the home directory, but generate the same 2-3 rows in the database)

Disks are cheap nowadays, so I wouldn't worry too much about the database sizing.  If we assume your data has no attachments, a 1.1 Gb zip file is a medium sized Jira and could consume up to 1.5Gb database space, so it's not going to be huge. 

One other point - do not use MariaDB, it's not supported.

Thanks for that Nic

Was hoping to use Maria Db as we're moving all our other real-estate to it, but no worries, I'll stick with MySQL.

Our Ops. manger is putting it on Rackspace so cost of storage is apparently not cheap.  I'll just tell him 30Gb min for each installation which should give me plenty of leeway  and allow me to leverage the new machines for a spot of extra work.

Thanks Again
