Limit ‘Files in Queue’ (new option)

Please, add a new option for file backup Limit ‘Files in Queue’

I have a client full backup size 7.5TB. UrBackup create full backups every 60 days.
Full size of storage is 15TB (btrfs), 3TB Avail.

When UrBackup does full file backup the ‘Files in Queue’ has very large numbers and I have errors:

FATAL: Could not free space. NOT ENOUGH FREE SPACE.
...
Backup failed

i.e. the files in the queue took up all the disk space (3Tb!!).

If you add option Limit ‘Files in Queue’ we can limit it and the storage will no longer completely fill up with queued files.
And we will not have error FATAL: Could not free space. NOT ENOUGH FREE SPACE.

I think it would be a very useful option!

Thank you in advance!
