Recovering data in increments for a large lost partition?

Question

This post relates to this other question of mine: Recovering Data

I'm finding a partition on TestDisk, but it's about 300 GB and I don't have an external hard drive on hand.

Is it possible to put pieces of the recovered data on a 16 GB flash drive, then bring it over to my other laptop? (The laptop has a terabyte hard drive so storage is not an issue)

Or is there anything else I can do, such as uploading the recovery to the cloud?

Thanks!

There are many options but It too broad to pass or expend all of them. Our refrence here is this simple recover method explained in:

Recovering broken or deleted NTFS partitions

It is always recommended to make dd or ddrescue image of the partition, then run testdisk/photorec through the image. Which means 02x 300GB free space is needed.

Both dd/ddrescue support start position and size. So you can read chunks one by one, copy to flash disk then merge them on PC2.

man dd
```
   count_bytes
          treat 'count=N' as a byte count (iflag only)

   skip_bytes
          treat 'skip=N' as a byte count (iflag only)

   seek_bytes
          treat 'seek=N' as a byte count (oflag only)
```
The disadvantage is that you have 20 rounds (300GB/15GB) of copy/paste each with a chunk of 15GB.

Setup an NFS share on PC2 and mount it on PC1, Recommended Ethernet cable connection instead of WiFi for quick transfer.

Reference: Ubuntu Server Guide: Network File System (NFS)

PC2: Server

Install NFS server
```
sudo apt-get install nfs-kernel-server
```

Setup share folder

sudo nano /etc/exports

/media/<username>/<partition-name>/<shared-folder>    *(rw,sync,no_root_squash)

Start the NFS service
```
sudo service nfs-kernel-server start
```

PC1: Client

Install NSF client tools
```
sudo apt-get install nfs-common
```

Mount the shared folder

sudo mkdir /mnt/pc2-nfs
sudo chown <username> <username> /mnt/pc2-nfs
sudo mount <pc2-ip>:/media/<username>/<partition-name>/<shared-folder>  /mnt/pc2-nfs
