Explanation:
Unity supports the File System Quotas which will enable a storage administrator to track and/or limit usage of a file system.
Limiting usage is not the only application of quotas. The quota tracking capability can be useful for tracking and reporting usage by simply setting the quota limits to zero.
Quota limits can be designated for users, or a directory tree. Limits are stored in quota records for each user and quota tree. Limits are also stored for users within a quota tree.
The usage is determined by "File Size" (which is the default) or "Blocks".
The File Size quota policy calculates the disk usage based on logical file sizes in 1K increments.
The block quota policy calculates the disk usage in file system blocks at 8KB file system blocks.
Hard and soft limits are set on the amount of disk space allowed to be used.
