如何backup一個大於2GB的檔案到 tape 中 ?

我有一些檔案大於2GB要backup到tape中

但因為tar and cpio的指令不支援大於2GB的檔案

所以有什麼方式可將檔案被到tape?

而且可方便的取回

如何backup一個大於2GB的檔案到 tape 中 ?

I do a test by using tar to backup a 3GB file into tape,

I don't see the 2G limitation on tar.

Here is my test for your reference.



By the way, have you try the fbackup to backup your files ?

如何backup一個大於2GB的檔案到 tape 中 ?

tar doesn't support > 2GB

Suggestion:

1. can get GNU tar from here: http://hpux.connect.org.uk/hppd/hpux/Gnu/tar-1.13.25/

2. 'fbackup' is far better than tar anyway (performance wise) and has many more options.

3. PHCO_29229:

Enhancement Request:tar has been enhanced to support backup of files upto 8GB from the earlier 2GB

For 11.00

看來是我 tar 的版本過舊需要上 patch

謝謝解決我的問題
