Hello All!

I use rsync to make back ups of my boot partition and my /home directory as they are on different drives.

How ever I did a restore for the boot one to go to another drive a SSD
instead of a DASD.

This is the back up one :

-!- cat rsync-root.sh

#!/bin/bash
time rsync -avvuhh --stats --delete --exclude=/dev --exclude=/proc --exclude=/mnt --exclude=/run --exclude=/tmp --exclude=/home
--exclude=/media --exclude=/sys /
/home/vince/Music2/Backups/SSD-Mageia-v7-HDD > rsync-root.log

rsync-root.err

exit 0
-!-

( line starting time continues down to 'rsync-root.err' )


This is the restore :

-!- cat rsync-restore-root.sh
#!/bin/bash
time rsync -avvuhh --stats --delete --exclude=/dev --exclude=/proc --exclude=/mnt --exclude=/run --exclude=/tmp --exclude=/home
--exclude=/media --exclude=/sys
/home/vince/Music2/Backups/SSD-Mageia-v7-HDD "/mnt/disk1" > rsync-restore-root.log 2 > rsync-restore-root.err
exit 0
-!-

The back up goes from root / to
/home/vince/Music2/Backups/SSD-Mageia-v7-HDD

The restore goes from /home/vince/Music2/Backups/SSD-Mageia-v7-HDD to

/mnt/disk1 and also tried "/mnt/disk1" as in above.

But both end up producing report in rsync-restore-root.err (should be .log)
but with a directory in my home directlry as 2/disk1 and SSD-Mageia-v7-HDD


I am confused :(

Is rsync changing destination location because the original source is not
the same as the restore ? as I can find no reference to that it the info
help file (via man rsync or info rsync).

The SSD partition IS mounted as /mnt/disk1 : - -

df - abbreviated :

/dev/sdc4 83G 57M 78G 1% /mnt/disk2
/dev/sdc6 118G 61M 112G 1% /mnt/disk3
/dev/sdc3 88G 18G 66G 22% /mnt/disk1

Mounted by root : - -

What on earth is rsync doing ?

I am trying to create an image of by DASD boot partition in the SSD so I
can switch to using it instead of the DASD by reconnecting the Sata cables around between the two and yes I suspect I will have to run the Mag
installer to fix up the /boot content and settings as they are different partitions with each drive.

No, rsync will move source location to target location as directed.

If you wanted to restore /boot from a location it would be

rsync args_here /src_loc/boot/ /dest_loc/boot

Pay careful attention to above trailing slashes.
Note that the /dest_loc argument does not have one.

If you want the source directory in a sub directory on /dest_loc you
would add a trailing /.

Example: rsync /src_loc/boot/ /dest/boot/ would create a sub directory
/boot in /dest/boot/

To clarify you would windup having a /dest/boot/boot

grub note: I have a multi-boot install, one of which is Cauldron.
For testing, I do a clean Cauldron net install and use rsync to backup /,
and change the boot location from /cauldron/boot to /mga7/boot.
That way mga7 is the master/production boot manager.

When I restore /cauldron from backup, and boot cauldron, grub feels
sad about what it sees.

I have to boot back into mga7, and reinstall grub with mga7 grub
and everything goes back to normal.

After your ssd boot restore, and you want to boot from ssd, then
you have to tell grub to use the ssd data.
