If you need to copy a whole folder from your server, you can use rsync to copy it securely. If there are numerous files, you can stop the process and carry it on later as rsync will not copy any files that are already present.
sudo rsync -v --progress --size-only firstname.lastname@example.org:/backup/2014-01-12/accounts/* /media/data/backup
The -v option stands for verbose and it shows what file it is currnetly up to. Progress gives you download/upload information and size-only will only check the size of the files and not the date and time stamp.
