I want to make a copy of a partition which I can use to replace it, |
| 2 |
if some catastrophe damages the partition or wipes it out ; |
| 3 |
it needs to be byte-byte identical, incl all permissions. |
| 4 |
|
| 5 |
Can I use 'dd' ? -- eg 'dd if=/mnt/xxx of=/mnt/yyy', |
| 6 |
where the partition has been mounted at /mnt/xxx |
| 7 |
& a USB stick has been mounted at /mnt/yyy . Will that do the job ? |
| 8 |
|
| 9 |
There seems also to be an issue re 'bs=<some number of bytes>' : |
| 10 |
what size is best ? i plan to use USB 3.0 for quicker copying. |
| 11 |
|
| 12 |
Does it matter how the USB stick is formatted ? |
| 13 |
Can I use a raw stick with the usual default VFAT formatting ? |
| 14 |
Might it be better to replace that with a Linux FS, eg Ext2 ? |
