Don't have a fully modern mac to check that on right now, but I suspect not, since it uses clock_gettime, a POSIX-compliant feature which the older version of OSX I have available definitely doesn't have. It was developed on Linux and Solaris so may need GNU features too.
I also checked in the fink repository, don't see it.
I suppose if the network is guaranteed to be slower than the tape you could just cat it, it'll never catch up until the tape's done. cat shouldn't care about the file size changing, it goes until EOF whatever that may be. Give the tape a head start to build up some steam.

Hi there
In my organisation we have a solaris network with /home being automounted from /export/home on a central file server (usual stuff) however, the guy who originally set this up only allocated 3gb to /export/home and now we are really struggling for space. I have a new 18gb disk installed... (3 Replies)
Hi, Im trying to take a database backup. one of the files is 26 GB. I am using cp -pr to create a backup copy of the database. after the copying is complete, if i do du -hrs on the folders i saw a difference of 2GB.
The weird fact is that the BACKUP folder was 2 GB more than the original one!

I have a zipped file that is ~ 10GB. I tried tarring it off to a tape, but I receive:
tar: <filename> too large to archive. Use E function modifier.
The file is stored on a UFS mount, so I was unable to use ufsdump.
What other options do I have? (I don't have a local file system large... (3 Replies)
Hi All
I am trying to copy files present in a partition (server 2) which is mounted to a different server (server 1) as tape drive is connected to it. I ran the below command to copy files within a partition:

We have 3 Unix servers all running SVR4 Unix 1.4. I have no problems copying files to and from 2 of the servers using either the rcp command or ftp but when i come to transfer large files to the third server the copy gives up part way through and crashes this server.

Hi,
I have a process which duplicates files for different environments. As the files arrive, my script (korn shell) makes copies of them (giving a unique name) and then renames the original file so that my process won't get triggered again.
I don't like it either, but it's what we were told to... (4 Replies)
I have a large file that I append entries to the end of every few seconds. Its grown to >150MB. Its basically a log file but a perl script is writing to it.

I am using a 4mm tape to backup my Unix system. However, I wanted to make a copy all of the files and archive headers (or just the archive headers if that's possible) created on one of my tapes to another 4mm tape. I only have one tape drive. Is there a command that will complete such task? ... (1 Reply)
Hello,
I'm new to this forum and like to first of all say hello to everyone.
I've got a really annoying problem at the moment.
I'm trying to rsync some files (about 200MB with one file of 120MB) from a Raspberry PI with raspbian to a debian server via rsync.
This procedure is stored in a... (3 Replies)

ansitape
ANSITAPE(LOCAL) ANSITAPE(LOCAL)
NAME
ansitape - ANSI standard tape handler
SYNOPSIS
ansitape [key] [keyargs] [files]
DESCRIPTION
Ansitape reads and writes magnetic tapes written in ANSI standard format (called ``Files-11'' by DEC). Tapes written by ansitape are
labeled with the first 6 characters of the machine name by default. Actions are controlled by the key argument. The key is a string of
characters containing at most one function letter. Other arguments to the command are a tape label and file names specifying which files
are to be written onto or extracted from the tape.
The function portion of the key is specified by one of the following letters:
r The named files are written at the end of the tape. The c function implies this.
x The named files are extracted from the tape. If no file argument is given, the entire contents of the tape is extracted. Note
that if the tape has duplicated file names, only the last file of a given name can be extracted.
t The names of the specified files are listed each time they occur on the tape. If no file argument is given, all files on the tape
are listed.
c Create a new tape; writing begins at the beginning of the tape instead of after the last file. This command implies r.
The following characters may be used in addition to the letter which selects the function desired.
f This argument allows the selection of a different tape device. The next word in the keyargs list is taken to be the full name of a
device to write the tape on. The default is /dev/rmt12.
n The n option allows the user to specify as the next argument in the keyargs list, a control file containing the names of files to
put on the tape. If the file name is '-', the control file will, instead, be read from standard input. The control file contains
one line for each file to be placed on the tape. Each line has two names, the name of the file on the local machine, and the name
it is to have when placed on the tape. This allows for more convenient flattening of hierarchies when placing them on tape. If
the second name is omitted, the UNIX file name will be used on the tape also. This argument can only be used with the r and c
functions.
l The l option allows the user to specify the label to be placed on the tape. The next argument in the keyargs list is taken as the
tape label, which will be space padded or truncated to six characters. This option is meaningless unless c is also specified.
v Normally ansitape works relatively silently. The v (verbose) option causes it to type information about each file as it processes
it.
b The b option allows the user to select the blocksize to be used for the tape. By default, ansitape uses the maximum block size
permitted by the ANSI standard, 2048. Some systems will permit a much large block size, and if large files are being put on the
tape it may be advantageous to do so. Ansitape will take the next argument of the keyargs list as the blocksize for the tape.
Values below 18 or above 32k will be limited to that range. The standard scale factors b=512 and k=1024 are accepted.
Ansitape will not copy directories, character or block special files, symbolic links, sockets, or binary executables. Attempts to put
these on tape will result in warnings, and they will be skipped completely.
FILES
/dev/rmt12
DIAGNOSTICS
A warning message will be generated when a record exceeds the maximum record length and the affected file will be truncated.
BUGS
Ansitape quietly truncates names longer than 17 characters.
ANSI 'f' format files can be read but not written.
Multivolume tapes can not be handled.
