Hello
I have been running websites based on joomla and K2 for several years
Suddenly I was faced with the problem of automatically deleting images from media / k2 / items / cache.
All files that are older than about a month are deleted.
Once I restored from backup but after one day they were gone again.
Can you explain to me what is happening and how to prevent it
thank you very much in advance :)

I tried to recreate the photos using the rebuild.php crypt. It took just over 8,000, and there are about 12,000 photos. Even if I set him to start, e.g. from 10,000, finish the execution immediately.
I did through the terminal
php -f
