To backup the directory, something like this...
tar czvf cyto_wallet.tar.gz cyto_wallet
then ask your vps provider for help on how to download cyto_wallet.tar.gz
once you download it, save it somewhere safe on your computer
I backed up the directory as you suggested. Then somehow I was able to successfully install a GUI on the VPS. I then located the archived backup (cyto_wallet.tar.gz) and opened it but alas, it was empty!!! I expected to at least find some sort of text file therein but there was not a single file in there. Please how I go about this whole backing up of a thing? i really don't want to lose my wallet when my g-cloud trial expires...
