Performing System Backups and Restorations
Solaris provides the utilities listed in Table 23. They can be used to back up data from disk to removable media and restore it.
You can use the fssnap command to create a read-only snapshot of a file system while the file system is mounted. A snapshot is a point-in-time image of a file system that provides a stable and unchanging device interface for backups. Unlike ufsdump, a UFS snapshot enables you to keep the file system mounted and the system in multiuser mode during backups. The snapshot is stored to disk, and then you can use Solaris backup commands like ufsdump, tar, and cpio to back up the UFS snapshot.
fssnap -F ufs -o bs=/var/tmp /export/home
Another way to back up your Solaris operating environment (not the data) is to create a Web Start archive. The Web Start flash archive feature can be used to back up your Solaris operating environment or to replicate an installation on a number of systems, called clone systems. While in single-user mode, you can use the flarcreate command to create the Web Start archive.
