The one version seems similar to what g4l does with the cd running, where the bigger version has a database system that needs to be setup. The one big difference is that g4l has a number of kernels on the cd image, since some hardware requires the latest kernels, and other hardware works with older version. So the user can boot from various kernels to find one that works with there hardware. I even have a method that can be used to add it to an ntfs partition to boot via grub4dos. As a side note, it seems at least for downloads the vast number of users are using windows for the download? About 200 - 300 per day. > > 2) Why aren't "backup/restore/image/clone" programs such as (1) above > integrated into LiveCDs that have most the Linux core, GUI, Network, > ..., > support? I believe both the smaller version of clonezilla and g4l are included on parted magic live cd? The g4l script can also be downloaded, and if the support programs are there, it can be run from various cds. Have in the past made packages that included the script and some programs that distro live cds didn't include. Did that for knoppix and finnix, and these same ones worked with others. G4L can backup and restore LVM partitions, but currently can not mount them directly. It can use LVM partitions thru the ftp to store images on LVM partitions. > > > For the moment, I use rsync for linux copy/clones/moves from > source to target partitions for the same hardware, and it works. > > I do these steps: > > (1) Boot with LiveCD > > (2) # rsync -ahHAX <source> <target> > > Notes: > (a) Optionally add 'z' argument if you want compression and > add 'v' if you want to see verbosity at the expense of transfer > speed. > (b) Abruptly stopped?

Exception is NTFSCLONE backups of ntfspartitions, which are file only backups. Also, since it is a bit level backup, pre-clearing of unused space makes the size of images much smaller. > (3) Setting MBR on boot or / (boot integrated) partitions: > # grub > find /grub/stage1 (or /grub/grub.cfg) > root (hX,Y) > setup (hX,Y) > quit > G4L can backup the MBR and partition table separately, or include it in a full disk image. > (4) # touch /.autorelabel; reboot (for SELinux) > Bit level makes all this the same. Thanks for the questions. In conclussion, G4L is a tool to do disk and partition images, as contrasted to file level backups. > FWIW, > Dan > > -- > users mailing list > users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines +----------------------------------------------------------+ Michael D.
