NAS Recovery Course - NAS Recovery Preparations Test

What do you need to try if the sum of sizes of partitions does not correspond to the size of a physical disk and you suspect the sector size is uncorrect?

divide the total size of partitions by 8
multiply the total size of partitions by 8
multiply the total size of partitions by 4

The information about a NAS coming from a client is often unreliable

yes, but it's better than nothing
no
yes

Check what you should ask a client about a NAS configuration

whether a client changed an array type
whether a client ever added disks
whether a client ever replaced disks
whether a client used disks of the same model in a NAS

Choose the advantage of disk clones compared to disk images

reliability
speed
convenience in storage and archival

Why they do not recommend storing several disk image files on the same disk when recovering data?

recovery will be too slow
the disk may degrade due to the frequent read requests

When recovering a NAS, it is always better to create disk image files rather than disk clones

false
true

The sum of partition sizes should be close to the size of a physical disk with both MBR and GPT disks

false
true

Check what information you can get if you know a NAS vendor and exact NAS model

Check those S.M.A.R.T. attributes pointing to the bad condition of a disk

Check based on what you can estimate the state of physical disks in a NAS

the words of a client
the S.M.A.R.T. attributes
sounds coming from the disks

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
