Hi. Before I get into all the gruesome details, my basic question is: =
How do I backup my system using linux so I can restore it *completely* =
in a simple manner without going through reinstalling everything (my =
Windoz system takes about 4 days by the time I get all the applications =
and patches etc. back where they were)?
I have a dual boot system with Windoz on the C and D drives (hda1, hda5) =
and Red Hat 7.0 on 3 remaining partitions. The last and largest =
partition is /image. It is currently empty and should have plenty of =
room (around 11 gb) for compressed backups of everything else.
I am about to install Mandrake 8.0, but first, I want to backup all of =
Red Hat (excluding the image partition itself and /mnt) to /image so I =
can restore it if I need anything or if I don't like Mandrake, etc.
I read the tar man and info pages and tried the following:
#bash
#backuprh - backup RedHat 7.0 to image partition
tar -c -P --preserve --same-owner -S --totals -w -z --file=3D/image/rh7 =
--exclude=3D/image -V rh7 /
I realize that I need to add something like --exclude=3D/mnt, but the =
main problem was that when I ran this it was asking for confirmation on =
every file (which would take a few years to complete). Can I just =
remove the -w option? I was hoping it would only ask for confirmation =
for an overwrite or other problem - not for everything.
The bottom line is - How do I make an easily restorable backup of Red =
Hat to my /image drive and what do I have to watch for or do when I =
install Mandrake so that Windoz and the /image partition are left =
intact? Also, once Mandrake is installed, are there any issues related =
to accessing the /image partition if I want to extract something from =
the archive?
As a side issue, the tar documentation refers to a backup script that =
should do a lot of this for me, but it didn't really tell me how it =
works. Also, it said that the restore script (kind of useful) didn't =
exist. What's the story on this?
I am big on backups, having been burnt numerous times. I am in the =
process of installing a cd-rw drive. One of the main reasons for =
getting it was so I could back up linux and Windoz and restore them if I =
have to. It seems like a good idea to backup Windoz partitions from =
linux as some sort of image backup because when linux is running, Windoz =
isn't, so no files are locked etc.
What about various backup utilities like bru and amanda? What's the =
easiest way to deal with this and keep it all straight so that when =
something breaks and panic starts to set in, there's a simple procedure =
to follow to get back to a known state without having to figure =
everything out again and worrying that you might leave out some =
important data or patches.
