# UNIX File Systems Archiving

The Commvault file archiving solution for UNIX File System enables you to move data to a secondary storage and use it to function as an archive copy.

Note

UNIX archiving does not support named pipe (FIFO) and symbolic link (symlink) files.

Note

For FreeBSD, the file system should be mounted with extended attribute option. If the extended attribute option is not enabled on the mount point, files will be backed up but not archived.

## What is Not Archived

By default, system specific files and folders are filtered out from archive operations. However, to bypass this restriction, you can add the sSTUB_PRUNE_EXCEPTIONS additional setting, which specifies the path to archive. For more information, see Configuring System Files to Skip during an Archive Operation.

The following file objects are automatically filtered out from archive operations by the system:

UNIX | Sparse files (For example, file archiver stub files) Install directory Job Results directory Log files directory /usr system directory /kernel system directory /etc system directory /tmp directory Extended attributes in the OES Linux data Stubs originating from an NSS volume on an OES Linux computer Files with extensions *.a, *.ksh, *.csh, *.sh, *.lib, and *.so are automatically filtered out of the subclient content by default. Similarly, files in the following directories are also skipped from archiving: /usr/**, /bin/**, /lib/**, /boot/**, /dev/**, /etc/**, /var/**, /tmp/**, /sbin/**, /lib64/**, /opt/**, /sys/**, /kernel/**, /devices/**, /proc/**, /selinux/**, /stand/**
AIX | /**/*.imp, /**/*.exp
FreeBSD | /rescue/**
Solaris | /platform/**
