Currently I create a ramdisk in Windows7 by using this RamDisk software by DataRam that has the ability to save RamDisk virtual disk image on shutdown and restore on Windows startup and sync data to hard disk automatically at specified time intervals.

I am looking for an application with similar functionality in Ubuntu

It is built into Ubuntu. For a RAM disk, do this:

sudo mkdir /mnt/ramdisk
sudo chmod 777 /mnt/ramdisk
sudo mount -t tmpfs -o size=256M tmpfs /mnt/ramdisk/

This will give you a 256M RAM disk mounted at /mnt/ramdisk.

  • @Jos Anyhow, thanks for the answer, no issues. If you know how to save data to disk periodically and save & auto mount data on shutdown, startup. Please update your answer.

    @Sampath For a periodical save, have cron execute an rsync command from the ramdisk to somewhere else. Write init.d scripts or Upstart scripts to backup (at shutdown) and restore (at startup) the data, again using a single rsync command. I think that covers the whole functionality of the product.
