How to create an image from a SSD drive? 11-29-2020, 07:23 AM #1
Hello,
I have an SSD drive that using kind of Linux. It is an SSD drive for MITEL 3300 switch: https://www.telecomspares.com/images/icp...i%20II.jpg
I want to create a backup from it. The SSD drive has below structure:
Code:
Code:
$ lsblk -f
NAME FSTYPE LABEL UUID                                FSAVAIL FSUSE% MOUNTPOINT

sdc                                                                  
├─sdc1
│    vfat  /sysro
│                020C-0000                                          
├─sdc2
│    vfat  /db  0257-0000                                          
├─sdc3
│    vfat  /vmail
│                02F6-0000                                          
├─sdc4
│                                                                    
├─sdc5
│    vfat  /sysro
│                036A-0000                                          
├─sdc6
│    vfat  /db  037F-0000                                          
└─sdc7
    vfat  /unused
                  03FA-0000
First, I unmounted all of the partitions:
Code:
$ sudo umount /dev/sdcX
Then, used below command to create a clone:
Code:
Code:
$ sudo dd if=/dev/sdc of=/home/jason/SSD.dd
234441648+0 records in
234441648+0 records out
120034123776 bytes (120 GB, 112 GiB) copied, 2850.17 s, 42.1 MB/s
And:
Code:
Code:
$ file SSD.dd
SSD.dd: DOS/MBR boot sector; partition 1 : ID=0x6, active, start-CHS (0x0,1,1), end-CHS (0x8f,254,63), startsector 63, 2313297 sectors; partition 2 : ID=0xb, start-CHS (0x90,0,1), end-CHS (0x3ea,254,63), startsector 2313360, 13799835 sectors; partition 3 : ID=0xc, start-CHS (0x3eb,0,1), end-CHS (0x3ff,254,63), startsector 16113195, 29543535 sectors; partition 4 : ID=0xf, start-CHS (0x3ff,0,1), end-CHS (0x3ff,254,63), startsector 45656730, 188784918 sectors
After it, I plugged another SSD drive with the same capacity and executed below command to recover the image to this new SSD drive:
Code:
Code:
# dd if=SSD.dd | pv | dd of=/dev/sdc bs=1M
234441648+0 records iniB/s] [                                              ]
234441648+0 records out
120034123776 bytes (120 GB, 112 GiB) copied, 4376.66 s, 27.4 MB/s
111GiB 1:12:56 [26.2MiB/s] [                                              ]
1+2129501 records in
1+2129501 records out
120034123776 bytes (120 GB, 112 GiB) copied, 4415.03 s, 27.2 MB/s
But, when I plugged this new SSD to the switch then it doesn't work!


Thank you.
