Seeking comments about managing Oracle's Alert log

Question

Good morning,
Alert logs can often be very useful.
I am forming the opinion that it would probably be a good idea to keep a backup of the alert logs for, maybe, a 3 to 6 months sliding window.
I would like to know the views of the forum members on the subject of alert log backups, including how long the backups (if any) are kept. Actual practice on the subject in production environments is greatly appreciated.
Thank you for taking the time to comment on the subject,
John.

Hello Asif,

Yes , may be you need to open a SR in metalink and they may ask something old incident. For this reason you need to check the old alert log content. That's why I suggest to keep the alert log for production environment for 3/4 years.

I had not thought about someone asking for an incident that would be over a year old but, I can see that on occasion having the records might be useful.

Now a days storage are cheap so it's not that critical to store the alert log files.

I completely agree. I was more concerned about managing that many logs... on the other, they are just flat files, not that hard to manage.
Thank you,
John.
