SME Dump Disk Backup Disk with dd

If you plan to update or make a bigger dist upgrade to a new Version ( 7.5.1 > 8.0.7)

you can use the powerful tool diskdump "dd" to do this. Login as root on ssh and do:

dd if=/dev/sda | ssh root@backupserver "(cat > sme-backup.img)"

Note: The sme-backup.img is placed into /root, monitor the disk space at the Backup Server with:

watch df 

Attention: This is a not very secure option to backup, cause broken transfers can't be restarted at broken steps!
