Full Discussion: Which is suitable Tar or Backup command????
Operating Systems AIX Which is suitable Tar or Backup command???? Post 302236185 by shockneck on Monday 15th of September 2008 03:19:38 AM

Depending on the AIX oslevel you will encounter different file size limits of AIX tar. The 2GB limit exists till about AIX 5.1. Recently you could archive files bigger than the limit officially announced. There are several ways around this file size limitation, e.g. you could use pax which uses tar format but handles bigger files (IIRC up to 8GB) or you could use gnu tar from the AIX Linux Toolbox that hasn't this POSIX limitation build in. However, as you are going to archive database files which could not only be large but also consist of sparse files the only program I'd recommend is AIX backup and restore.

gpodder-backup

GPODDER-BACKUP(1)						   User Commands						 GPODDER-BACKUP(1)

NAME

       gpodder-backup - Backup and restore utility for gPodder user data

SYNOPSIS

       gpodder-backup [--create|--extract] <archive.gpo.tar.gz> [options] gpodder-backup --purge

DESCRIPTION

       This utility can be used to create a dump of the current gPodder data (configuration files + downloads), optionally replacing the real con-
       tents of the download folder with zero-byte files (for submitting your data to a bug report without having to transfer lots of data).

OPTIONS

       --version
	      show program's version number and exit

       -h, --help
	      show this help message and exit

       -c <FILE>, --create=<FILE>
	      Create a new archive

       -x <FILE>, --extract=<FILE>
	      Extract an existing archive

       -f, --fake-downloads
	      Store downloads as zero-byte files in backup

       -n, --no-covers
	      Do not include cover files in archive

       -D <DIR>, --destination=<DIR>
	      Extract downloads in different folder

       -P, --purge
	      Remove current data (can be combined with --extract)

USAGE FOR BUG REPORTING

       This command is useful if you want to report a bug in gPodder:

       gpodder-backup --create bug123.gpo.tar.gz --fake-downloads
	      Backup your current data to file bug123.gpo.tar.gz, but don't store download data (create zero-size dummy files  instead).  You  can
	      then attach bug123.gpo.tar.gz to the bug report.

       If you are instructed to try gPodder from a "clean state", you can use the following command (be sure to backup your data before!):

       gpodder-backup --purge
	      Remove all gPodder data, so you can start from a clean state

EXAMPLES

       gpodder-backup --create today.gpo.tar.gz
	      Backup your current data to file today.gpo.tar.gz

       gpodder-backup --extract mybackup.gpo.tar.gz
	      Restore (without purging) the contents of mybackup.gpo.tar.gz

       gpodder-backup --extract default.gpo.tar.gz --purge
	      Remove current data, then restore the contents of default.gpo.tar.gz

       gpodder-backup --purge
	      Remove all gPodder data, so you can start from a clean state

EXTRACTING FAKED DOWNLOADS

       Please  note  that  any	existing  downloads will be overwritten with zero-byte files when using the --extract option of the gpodder-backup
       utility with a backup created with --fake-downloads
