Casually I cheked the inodes on my server and I found many old fiels o the upgrades, I wm courious to know if I can delete them by hand or not:
823 files: MYPATH/upload/upgrades/patch/SuiteCRM-Upgrade-7.12.x-to-7.12.8-restore/vendor/nesbot/carbon/src/Carbon/Lang
823 files: MYPATH/upload/upgrades/patch/SuiteCRM-Upgrade-7.12.x-to-7.12.7-restore/vendor/nesbot/carbon/src/Carbon/Lang
822 files: MYPATH/upgrades/patch/SuiteCRM-Upgrade-7.12.x-to-7.12.6-restore/vendor/nesbot/carbon/src/Carbon/Lang
and other 14
folders similat to these, totally more of 10.000 files…
Yes, you can delete those safely, you only lose the ability to restore those packages from Module loader. Which would be a complicated job any way, except for the latest package perhaps.
You might also want to check if your session directory (called session.save_path in phpinfo) is getting cleaned up properly. You don’t have to do anything there when things go well. But sometimes thousands of files accumulate.
