Log analytics retention greater than 730 days

Question

Hello,

We need to have a 10-year retention for the data we keep in log analytics.
We have seen that in preview it is retaining them for up to 7 years.
There is some standard way (or walkaround) to retain them for longer: 10, 20 years...

Thanks

Hello @JULIOFORNIESGANCEDO-9216,

In Log Analytics, you can only retain the data for a maximum 7 years period:

• 2 years in the interactive retention (workspace retention)
• 5 extra years in the archive retention

If you need to keep the data more than that, you can make use of Data Export feature that will allow you to export data from specific / all tables to an Azure Storage / Azure Event Hub / etc. (from which you can pull that data in any storage solution).

I hope this helps.

George

Hi

Thanks for reaching out to Microsoft Q&A.

Not possible currently for more than 7 years, but you can try to export like George has pointed out. I think that is an adopted solution most of the companies follow for LTR of log analytics data.

If you wanna have the same KQL magic in-place, have a look at Azure Data Explorer as an alternative archive option.

It's cheaper and you can store your data as long as you want. Actually, this is a PaaS version of Log Analytics.
