Rationale behind the concept
giis takes snapshot of the ext3/ext2 file system at a specified point of time.A full backup of a data will need large disk,If you accidently deleted a file,retrieve it from backup data.
Obvious disadvantage is that backup takes long time to complete and it consumes large disk space.
In order to recover a missing file,such a huge resource utiliztion can be avoided with the help of giis.
giis performs snapshot of the file system 'meta data' not data,hence lot of disk space saved.Thus accidently deleted files are recovered with saved meta data.
Even if the file is fragmented, meaning that the data occupied on the disk is not in sequence,giis can retrieve the file.This process is usually much safer in aiding recovery of deleted files than the data recovery process.
