Mac data recovery when FileVault Sparse image cause data loss

Apple Mac

Mac Machines are quite advanced in their architecture and are incorporated with various features for data safety. FileVault is such a type of application that facilitates the encryption of the data in your home directory/folder.

While the FileVault protection is 'ON', the home folder/directory transforms into an encrypted disk image. Then using the 'secure erase' option, you can erase the files that has already been copied into the FileVault. However, if there happens any problem, which effects or stops the process, then the data may get lost and can only be recovered back through any efficient Mac data recovery software.

What is Filevault ?: 

Filevault is a utility meant to protect files in a Mac machine. This utility comes included in all the Mac  OS, Mac OS X 10.3.9 and later. FileVault derives a key from the user login id, password and encrypts the home directory using the Advanced Encryption Standard  Or AES algorithm. The encrypted file system is mounted and unmounted when the user logs into or out of the system. FileVault saves the data as a single large file, that is a Sparse Disk Image and the data can be backed up by breaking the image into individual Sparse bands. However, there is a drawback lies with  FileVault, as it doesn't make the image of the whole drive and Mac Time Machine doesn't take back up of individual data.
