<h1 class="topictitle1">Backing up files using Linux utilities and applications</h1>
|
|
<div><p>This topic discusses backup and recover using Linux<sup>®</sup> utilities.</p>
|
|
<p>At the time of writing, not all the applications listed here had been tested
|
|
for use with iSeries™ tape
|
|
drives. However, even though a particular Linux backup application has not been
|
|
tested for use with iSeries tape drives, this does not mean that the
|
|
application will not work. You need to test your backup application to determine
|
|
if it is compatible with the tape drive installed on your iSeries server. </p>
|
|
<p>When performing a backup you should close any operation that is using files
|
|
on the Linux file
|
|
system or the directory you intend to back up. Though native Linux backup
|
|
utilities do back up files that are in use, we recommend that you close all
|
|
open files and the operations using them so as to preserve the latest file
|
|
updates and avoid any data corruption. </p>
|
|
<p>If the file system is network file system (NFS) then file locking occurs
|
|
when the file residing on NFS is in use by an operation. Creating a tar or
|
|
cpio backup archive can fail if you try to include such files. Commercial
|
|
applications like IBM<sup>®</sup> Tivoli<sup>®</sup> Storage Manager (TSM), ARCserve, Veritas, or
|
|
Legato provide better facilities for backing up data as they provide open
|
|
file agents. Even so, it would be safe practice to stop the operation that
|
|
is locking the file over NFS before backing it up. </p>
|
|
<div class="section"><h4 class="sectiontitle">Determining the tape device block size</h4><p>Before you
|
|
begin your backup using a Linux utility or application, you need to determine
|
|
the block size of the tape device you are using. To do this you run the magnetic
|
|
tape (mt) command, for example:</p>
|
|
<pre>mt -f /dev/st1 status</pre>
|
|
<p>Replace
|
|
/dev/st1 with the device name of your tape drive.</p>
