(TO BE OBSOLETED)

WARNINGS

The fbackup, frecover, and ftio commands are deprecated for creating new archives. In a future

HP-UX release, creation of new archives with these commands will not be supported. Support will be con-

tinued for archive retrieval. Use the standard

pax

command (portable archive interchange) to create

archives. See pax(1).

Because of industry standards and interoperability goals,

ftio does not support the archival of ﬁles larger

than 2GB or ﬁles that have user/group IDs greater than 60K. Files with user/group IDs greater than 60K

are archived and restored under the user/group ID of the current process.

ftio operates using System V shared memory and semaphores. The resources committed to these func-

tions are not freed automatically by the system when the process terminates.

ftio does this only when

it terminates normally, or when it terminates after receiving one the following signals:

SIGHUP, SIGINT,

SIGTERM. Any other signal is handled in the default manner described by signal(2). Note that the

behavior for

SIGKILL is to terminate the process without delay. Thus, if

ftio receives a SIGKILL sig-

nal (as might be produced by the indiscriminate use of

kill -9

(see kill(1)), system resources used for

shared memory and semaphores are not returned to the system. If it becomes necessary to terminate an

invocation of

ftio, use kill -15 instead. Current system usage of shared memory and semaphores

can be checked using the

ipcs command (see ipcs(1)). Committed resources can be removed using

ipcrm (see ipcrm(1)).
