backup(1M) backup(1M)
NAME
backup - backup or archive file system
SYNOPSIS
[-archive]
DESCRIPTION
The command uses find(1) and cpio(1) to save a archive of all files that have been modified since the modification time of on the default
tape drive should be invoked periodically to ensure adequate file backup.
The option suppresses warning messages regarding optional access control list entries. backup(1M) does not backup optional access control
list entries in a file's access control list (see acl(5)). Normally, a warning message is printed for each file having optional access
control list entries.
The option causes backup to save all files, regardless of their modification date, and then update using touch(1).
prompts you to mount a new tape and continue if there is no more room on the current tape. Note that this prompting does not occur if you
are running from cron(1M).
The option causes to start a file system consistency check (without correction) after the backup is complete. For correct results, it is
important that the system be effectively single-user while is running, especially if is allowed to automatically fix whatever inconsisten-
cies it finds. does not ensure that the system is single-user.
You can edit to customize it for your system. Several local values are used that can be customized:
specifies which directories to back up recursively (usually
meaning all directories);
file name where start and finish times, block counts, and error messages
are logged;
file name whose date is the date of the last archive;
file name that is checked by
to remind the next person who logs in to change the backup tape;
file name where start and finish times and
output is logged.
You may want to make other changes, such as whether or not does automatic correction (according to its arguments), where output is
directed, other information logging, etc.
In all cases, the output from is a normal archive file (or volume) which can be read using with the option.
File Recovery
creates archive tapes with all files and directories specified relative to the root directory. When recovering files from an archive tape
created by you should be in the root directory and specify the directory path names for recovered files relative to the root directory When
specifying the directory path name for file recovery by do not precede the leading directory name with a slash. If you prefer, you can
also use with a option to determine how files and directories are named on the archive tape before attempting recovery.
WARNINGS
Refer to in cpio(1).
When runs out of tape, it sends an error to standard error and demands a new special file name from
To continue, rewind the tape, mount the new tape, type the name of the new special file at the system console, and press
If is being run unattended from cron(1M) and the tape runs out, terminates, leaving the process still waiting. Kill this process when you
return.
