Remarks

Note: The

fbackup, frecover, and

ftio commands are deprecated for creating new archives. See

WARNINGS for more information.

DESCRIPTION

frecover reads media written by the fbackup command. Its actions are controlled by the selected

function -r, -R, -x,

-V,or-I.

The function performed by

frecover is speciﬁed by one of the following options:

-r The backup media is read and the contents are loaded into the directories from which they

were backed up. This option should only be used to recover a complete backup onto a clear

directory or to recover an incremental backup after a full level-zero recovery (see

fbackup (1M)). This is the default behavior.

-x The ﬁles identiﬁed by the -i, -e, and -g options (see below) are extracted or not extracted

from the backup media. If a ﬁle to be extracted matches a directory whose contents have

been written to the backup media, and the -h option is not speciﬁed, the directory is recur-

sively extracted. The owner, modiﬁcation time, and access control list (including optional

entries, unless the -A option is speciﬁed) are recovered. If no ﬁle argument is given (includ-

ing an empty graph ﬁle), all ﬁles on the backup media are extracted, unless the

-h option is

speciﬁed.

-I path The index on the current volume is extracted from the backup media and is written to path .

-V path The volume header on the current volume is extracted from the backup media and is written

to path . The following ﬁelds from the header are extracted in the format label :value with

one pair per line.

Magic Field On valid fbackup media, it contains the value

FBACKUP*LABEL (HP-UX 11i Version 3 and beyond). Previ-

ous values of this ﬁeld were FBACKUP_LABEL

(between HP-

UX 10.20 and HP-UX 11i Version 2 inclusive) and

FBACKUP

LABEL (before HP-UX 10.20).

Machine Identification

This ﬁeld contains the result of uname -m.

System Identification

This ﬁeld contains the result of uname -s.

Release Identification

This ﬁeld contains the result of uname -r.

Node Identification This ﬁeld contains the result of uname -n.

User Identification This ﬁeld contains the result of cuserid().

Record Size This ﬁeld contains the maximum length in bytes of a data

record.

Time This ﬁeld contains the time fbackup was started.

Media Use This ﬁeld contains the number of times the media has been

used for backup.

frecover(1M) frecover(1M) (TO BE OBSOLETED) Volume Number This field contains a # character followed by 3 digits, and identifies the current volume in the backup. Checkpoint Frequency This field contains the number of data records between checkpoints. Fast Search Mark Frequency This field contains the number of files between fast search marks for backups made with DDS tape drives. Index Size This field contains the size of the index.

frecover(1M) frecover(1M) (TO BE OBSOLETED) i /usr It is also possible to skip files by using the -e option. For example, if a user wants to recover all of /usr except for the subgraph /usr/lib, the graph file contains two entries: i /usr e /usr/lib If the graph file is missing, frecover exits with an error message. An empty graph file results in recovering all files on the media. -h Extract the actual directory, rather than the files that it references.
PAGE 4
frecover(1M) frecover(1M) (TO BE OBSOLETED) -S skip frecover does not ask whether it should abort the recovery if it gets a media error. It tries to skip the bad block or blocks and continue. Residual or lost data is written to the file named by skip . The user can then edit this file and recover otherwise irretrievable data. -X Recover files relative to the current working directory. Normally frecover recovers files to their absolute path name.

frecover(1M) frecover(1M) (TO BE OBSOLETED) The utility set comprised of fbackup and frecover was originally designed for use on systems equipped with not more than one gigabyte of total file system storage. Although the utilities have no programming limitations that restrict users to this size, complete backups and recoveries of substantially larger systems can cause a large amount of system activity due to the amount of virtual memory (swap space) used to store the indices.
