How to Restore a File System
After backing up the file system, you can restore it using the vxrestore command. First, create and mount
an empty file system. To restore a VxFS snapshot file system, use the syntax:
vxrestore [-v] [-x] [filename]
-v Specifies verbose mode.
-x Extracts the named files from the tape.
filename The file or directory to restore. If filename is omitted, the root directory (and thus the
entire tape) is extracted.
Example A-13 To restore a VxFS snapshot file system from the tape /dev/st1 into the
mount point /restore
Enter:
# cd /restore
# vxrestore -v -x -f /dev/st1
Using Quotas
You can use quotas to allocate per-user quotas on VxFS file systems.
See Chapter 7, “Quota,” on page 111 and the following manual pages for more information about the
quota, quotaon, quotaoff, and edquota commands and their available options:
• edquota(1M)
• quota(1M)
• quotaon(1M)
• quotaoff(1M)
