Please clean the disk https://crm.hlr.ua/

Good afternoon.
You don't have junk/temporary files on the server, etc.
All you can do is reduce the number of database backups.
Now DB backups take ~20 GB (copies for 9 days ~ 2.17 GB each), if you reduce it to 5, then about 9 GB will be added.
Place is currently occupied:
19.5 GiB - database copies;
34 GiB - database;
406 GiB - Boxing
Total: ~460 GiB + system ~5 GiB
Now available:
File System Size Used Dst Used % Mounted In
/dev/sda4 489G 465G 4.3G 100% /
Since the main disk space is occupied by box files (client files), as an option:
- Add a new disk to the system, sufficient volume (as an example 1TB), transfer client files there;
- Or if there are files that are not needed, then you can set up an action to clean up old files;
