<p>IA migration §6: new Data Lifecycle Policy (P2.13) (via create-page on MediaWiki MCP Server)</p> <p><b>New page</b></p><div>Data on Anunna moves through a lifecycle: active working data, data you keep but no longer actively use, and data that is no longer needed. Managing that lifecycle keeps storage available and costs under control.<br /> <br /> == Active data ==<br /> <br /> While you are working on it, data lives on the fast [[Compute Storage|Lustre]] filesystem. Temporary working data on &lt;code&gt;/lustre/scratch&lt;/code&gt; is not kept indefinitely — it may be purged automatically once the filesystem fills up (see [[Compute Storage]] and [[Backup Policy]]).<br /> <br /> == Archiving data you keep ==<br /> <br /> When you are finished with data but want to keep it, move it to [[Archival Storage|archival storage]]. Datasets there that are no longer actively used are moved to long-term tape archive automatically by the [[Archival Storage#Tapeworm|Tapeworm]] service, freeing the warm storage tier.<br /> <br /> == Removing data ==<br /> <br /> Delete intermediate and temporary data you no longer need — it keeps the cluster usable and your costs down. Remember that [[Backup Policy|backups]] are limited, so be sure before you delete.<br /> <br /> &lt;!-- TODO: add the formal data-retention policy if one exists — how long different data is kept, any maximum retention, and what happens to data when an account or project closes. --&gt;<br /> <br /> == See also ==<br /> * [[Storage Systems Overview]]<br /> * [[Archival Storage]]<br /> * [[Backup Policy]]<br /> * [[Data storage best practices]]</div>
