I've backed up several files to tape using tar, and wish to list those that have backed up.
% tar cvf /dev/rmt/2un /s_1/oradata/pgpub/config.ora
a /s_1/oradata/pgpub/config.ora 2 tape blocks
But when I go to list the files:
% tar tvf /dev/rmt/2un
tar: tape read error

Hi,
Does anyone know if it is possible to tar files larger than 2GB? The reason being is they want me to dump a single file (which is around 20GB) to a tape drive and they will restore it on a Solaris box. I know the tar have a limitation of 2GB so I am thinking of a way how to overcome this.... (11 Replies)
Hi all,
I have a tar file and inside that tar file is a folder with additional tar.gz files. What I want to do is look inside the first tar file and then find the second tar file I'm looking for, look inside that tar.gz file to find a certain directory. I'm encountering issues by trying to... (1 Reply)
I have a tar file that contains multiple .Z files. Hence I need to issue a tar command followed by a gzip command to fully extract the files. How do I do it in a single command?
What I'm doing now is
tar xvf a.tar (this will output 1.Z and 2.Z)
gzip -d *.Z (to extract 1.Z and 2.Z) (9 Replies)

It is easy to create a tarball when you have files same extension
For eg:
You want to tar all files with the extension .log . This is easy
tar -cvf diagnose.tar *.log
I have two files with different extensions .log and .sh :
error.log
myscript.sh

My unzip command doesn't work for files that are greater than 4GB. Consider my file name is unzip -p -a filename.zip, the command doesn't work since the size of the file is larger. I need to know the corresponding 7z command for the same. This is my Unix shell script program:

restor
RESTOR(8) System Manager's Manual RESTOR(8)NAME
restor - incremental file system restore
SYNOPSIS
restor key [ argument ... ]
DESCRIPTION
Restor is used to read magtapes dumped with the dump command. The key specifies what is to be done. Key is one of the characters rRxt
optionally combined with f.
f Use the first argument as the name of the tape instead of the default.
r or R The tape is read and loaded into the file system specified in argument. This should not be done lightly (see below). If the key is
R restor asks which tape of a multi volume set to start on. This allows restor to be interrupted and then restarted (an icheck -s
must be done before restarting ).
x Each file on the tape named by an argument is extracted. The file name has all `mount' prefixes removed; for example, /usr/bin/lpr
is named /bin/lpr on the tape. The file extracted is placed in a file with a numeric name supplied by restor (actually the inode
number). In order to keep the amount of tape read to a minimum, the following procedure is recommended:
Mount volume 1 of the set of dump tapes.
Type the restor command.
Restor will announce whether or not it found the files, give the number it will name the file, and rewind the tape.
It then asks you to `mount the desired tape volume'. Type the number of the volume you choose. On a multivolume dump the recom-
mended procedure is to mount the last through the first volume in that order. Restor checks to see if any of the files requested
are on the mounted tape (or a later tape, thus the reverse order) and doesn't read through the tape if no files are. If you are
working with a single volume dump or the number of files being restored is large, respond to the query with `1' and restor will read
the tapes in sequential order.
If you have a hierarchy to restore you can use dumpdir(8) to produce the list of names and a shell script to move the resulting
files to their homes.
t Print the date the tape was written and the date the file system was dumped from.
The r option should only be used to restore a complete dump tape onto a clear file system or to restore an incremental dump tape onto this.
Thus
mkfs /dev/hp0a 4807
restor r /dev/hp0a
is a typical sequence to restore a complete dump. Another restor can be done to get an incremental dump in on top of this.
A dump followed by a mkfs and a restor is used to change the size of a file system.
FILES
/dev/rmt1 default file name
rst* temporary files
SEE ALSO dump(8), dumpdir(8), mkfs(8)DIAGNOSTICS
There are various diagnostics involved with reading the tape and writing the disk. There are also diagnostics if the i-list or the free
list of the file system is not large enough to hold the dump.
If the dump extends over more than one tape, it may ask you to change tapes. Reply with a newline when the next tape has been mounted.
Dump tapes made before the new ondisc directory structure will be converted automatically by restor .
BUGS
There is redundant information on the tape that could be used in case of tape reading problems. Unfortunately, restor does't use it.
