 Posted: Tue Feb 20, 2007 6:04 pm Post subject: [solved] Possible to copy/paste ALL files in / ? |
 |
|
If I want to make a backup, can I simply set up partitions on another drive and then copy all files from my current Gentoo to that HD?
(Afterwards I'll replug the HDs to make the new one master and all that.. And I'll run a quickie with the Gentoo CD to fix up Grub.)
I'm gonna switch harddrives, and I want my system exactly as it is now - but on the other HD..
Will this work?

| You could make a stage4 install on your second drive. There are guides on the web. Tell me your progress if you try it! |

Yeah I know about the stage 4 scripts. But I don't want to have a stage 4.
I don't want to backup a part of my system - I want to backup everything on the partition..
I don't want to tar anything, or do anything strange.
I just want to "cp hda1/* hdb1/".
And then switch the drives, and run Gentoo CD to fix the MBR on the new disk (I'll wipe the old one).
Humm, would this work? |

Are these two discs IDE, or IDE and SATA, or two SATA discs.
There are certain directorys which shouldn*t be copied, because that makes no sense. Especially /proc .... |

use rsync - cause rsync rocks
| Code: | rync -varn --filter='/dev /proc' /mnt/backups/myBackup
tar cvf backup.tar myBackup
gzip backup.tar |
the n option is for a dry run. ie: tell me what you're going to do before you go and do it. The filter option does what it sounds like it should do and excludes those files from the list that rsync builds before it's going to copy.
backing up everything in / isn't generally the way to go about it, have a peep at this from the wiki http://gentoo-wiki.com/HOWTO_Backup
And then i just re read your post and realised that i'd missed the point  You broke your MBR? so you really need to just reinstall grub in your mbr? |

Thanks for the info, I'll try to fix the partitions right and sort of do a
I'll see what happens. I've already backed up all my important data, so in the worst case I'll have to spend 3 days setting up a fresh Gentoo..
Wish me luck.  |

i have had troubles with copying the / to other partitions all dont get copied. some not readable some not movable.
moving has worked better than copy. thought grub has to be installed again and fstab to be rewritten.
hda hdc change of location it does not agree with. if you move it is one chance of working or reinstall. copying gives second third chances also.
in my experience reinstall new gentoo is far easier than end up with a copied / moved broken borked system. i was not at all happy with the performance of the moved install.

Well, I just wanted to post my success.
I'm currently using the new harddrive to write this, and everything seems to work just fine..
Cheers! |

Unfortunately I forgot to install grub on the mbr of the target drive!  |
