You can attach multiple Block Storage volumes to the same droplet (up to 5 volumes).
Then you could attach another volume to your current droplet, and configure it as another device in Ubuntu, and then copy data with the regular cp command.
thnx @hansen
Actually i have an 2 droplet and both have an different different block storage so i want to copy one droplet block storage data to second droplet block storage.
or else how to access one droplet block storage to second droplet.
Ahhh, then it's much more simple. Keep everything as it is now. I would recommend that you go to the control panel and take a snapshot before copying data around.
You can use the command scp, which creates a SSH tunnel and then copies data.
Login to the droplet you want to copy data from.
scp -pr /path/from user@droplet-ip-address:/path/to/
#Example
#scp -pr /volume-old/photos root@12.34.56.78:/volume-keep/media/
@hansen
Actually i can't able to login this droplet because it is under Ddos attack. But i have an snapshot of the block storage.
Uhm, okay, then detach the volume from the DDoS-droplet and then attach it to the working droplet, mount the volume in your OS, and then just use the cp command.
