Filesystem Recovery Course - File Storage Basics Test
What is an alternative name for cluster?
chunk
block
sector
stripe
A filesystem, if possible, tries to allocate clusters sequentially
false
true
What is fragmentation?
when two files have identical fragments
when a file is stored in several non-contiguous fragments
Check optional properties for a file
size
data and time of file creation
access rights
name
file extension
content
What is a sparse file?
a file containing a compressed block
a file containing zeros which are not actually stored on the disk
a file consisting of more than one fragment
a file containing more than two identical blocks
What is a compressed file?
a file consisting of more than one fragment
a file containing zeros which are not actually stored on the disk
a file containing fragments stored on disk in compressed form
a file containing more than two identical blocks
How does deduplication work?
a filesystem monitors that exactly one copy of each file metadata block is stored
a filesystem monitors that no more than two copies of each data block is stored
a filesystem compresses data before writing it to the disk
a filesystem monitors that exactly one copy of each data block is stored
Check what makes carving impossible
checksums
sparse storage
journaling
deduplication
compression
fragmentation
copy-on-write
What is carving?
discovering files by searching the disk by file header signatures
discovering files by searching the disk by file names
discovering files by searching the disk by file hashes
Check filesystem features which facilitate data recovery
deduplication
compression
checksums
copy-on-write
fragmentation
journaling
