Full Discussion: Do incremental backup without tar files up
Top Forums UNIX for Advanced & Expert Users Do incremental backup without tar files up Post 302434846 by cjcox on Monday 5th of July 2010 11:57:11 AM

Just me... I'd use Linux as the holder of the backup data. rsync, as mentioned is the best solution, but in lieu of that, sounds like you'll have to write a screen scraping (?) ftp like manager to loop through and grab everything. Could mean multiple passes. Might help to know the target system? You'd be surprised at what people have experience with.

I'd use Linux, because assuming you can roll through and pull the whole tree across ala ftp style (maybe you're system supports scripting on xfer??).... then you can use the GNU cp -l option to create a link shadow of the backed up area... this is a cheap mans snapshotting. So as long as the backup and shapshots on the receiving system are within the SAME filesystem, you can use this cheap snapshot mechanism to keep track of multiple days... AND you can browse through it all.

vgcfgbackup

VGCFGBACKUP(8)						      System Manager's Manual						    VGCFGBACKUP(8)

NAME

       vgcfgbackup - backup volume group descriptor area

SYNOPSIS

       vgcfgbackup [-d|--debug] [-h|--help] [-v|--verbose] [VolumeGroupName...]

DESCRIPTION

       vgcfgbackup  allows you to backup the metadata or Volume Group Descriptor Area (VGDA) of one to all volume groups to files in /etc/lvmconf.
       If you don't give any volume groups in the command line, all of them will be backed up.	This DOESN'T backup user/system  data  in  logical
       volume(s)!   To	restore  volume  group	descriptor area backups see the vgcfgrestore(8) tool.  A 10 step history is backed up in /etc/lvm-
       conf/VolumeGroupName.conf and  /etc/lvmconf/VolumeGroupName.conf.[1-9].old. This enables you to restore your volume group configuration	up
       to 10 steps back in the backup history.

   OPTIONS
       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about vgcfgbackup's activities.

DIAGNOSTICS

       vgcfgbackup returns an exit code of 0 for success and > 0 for error:

       1  error doing backup

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line
