About Disk Archiving

Archiving is the process of copying a file from online disk to archive media. With

disk archiving, the archive medium is online disks in a file system.

Disk archiving can be implemented so that the files are archived from one Sun

StorageTek SAM file system to another file system on the same host computer or to

another file system on a different Sun Solaris host. When disk archiving is

implemented using two host systems, the systems involved act as a client and a

server, with the client system hosting the source files and the server system being the

destination system that hosts the archive copies.

The file system to which the archive files are written can be any UNIX file system.

However, if disk archive copies are written to a different host, the host must have at

least one file system installed on it that is compatible with the Sun StorageTek SAM

software.

The archiver treats files archived to disk volumes the same as files archived to

volumes in a library. You can still make one, two, three, or four archive copies. If you

are making multiple archive copies, one of the archive copies could be written to

disk volumes while the others are written to removable media volumes. In addition,

if you typically archive to disk volumes in a Sun StorageTek SAM file system, the

archive file copies are themselves archived according to the archiver.cmd file rules

in that file system.
