==== FOSS Tool Recomendations ====
[[https://swiki.ics.uci.edu/doku.php/software:commontools|Recommended tools]], free and open source.   Let us know if you have more suggestions.

==== User Account Inode Quota ====

Beginning on July 9th, an inode quota will be applied to all undergrad and grad home directories. This will not affects other storage spaces such as /extra directories. Inode refers to the number of files in a directory. Having too many inodes takes away space that could be used for data storage. It also affects backups as each file is an entry in a database. When the number of inodes reach critical usage, it affects all users whose home directories are on the same volume.

The quota will be set at 100,000 inodes. 

If you suspect that you are using too many inodes, please login to one of our servers such as openlab.ics.uci.edu and run the following command:

<code>find . -type d -name ".snapshot" -prune -o -print | wc -l</code>
