Check optional properties for a file
content
name
access rights
data and time of file creation
file extension
size
How is a record storing file metadata and pointers to file content called in Linux?
inode
indirect block table
directory
MFT record
short form directory
group descriptor
A filesystem, if possible, tries to allocate clusters sequentially
false
true
Check what makes carving impossible
checksums
copy-on-write
journaling
sparse storage
compression
deduplication
fragmentation
What is a minimum unit of disk space a physical device operates with?
sector
cluster
chunk
stripe
What is fragmentation?
when two files have identical fragments
when a file is stored in several non-contiguous fragments
How does deduplication work?
a filesystem monitors that exactly one copy of each file metadata 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
a filesystem monitors that no more than two copies of each data block is stored
Check properties a file required to have
name
content
access rights
data and time of file creation
size
Check filesystem features which facilitate data recovery
deduplication
compression
copy-on-write
fragmentation
checksums
journaling
What is a compressed file?
a file containing more than two identical blocks
a file containing fragments stored on disk in compressed form
a file consisting of more than one fragment
a file containing zeros which are not actually stored on the disk
