A

last full backup and last differential
backup

25

in Full Backup + Differential Backup, day 1 is functioning typically and fresh
supplementary data is available

A

back up operation

26
Q

in Full Backup + Differential Backup, Day 2 which is backed up through a

A

differential backup.

27
Q

Type of back up that all changes that take place since first full
backup copy are backed up.

A

Incremental forever Backup

28
Q

Disadvatnage:
Restores require full backup and all incremental backup copies to perform a restore
making it complex

A

Incremental forever back up

29
Q

Advantages
* Reduces length of backup window
* No need for scheduling the full backup
* Reduces load on network
* Availability of data
* Transparency in restoration procedure, automated restoration

A

Incremental forever back up

30
Q

an initial full backup is conducted and then
incremental backups are performed consecutively.

A

Synthetic Backup

31
Q

the name suggests this backup is
not created from original data

A

Synthetic Backup

32
Q

Advantages
* Consumes less time to perform backup
* Costs are reduced
* Lower restore time

A

Synthetic Backup

32
Q

Disadvantages
* This backup cannot be first backup performed on a system
* It cannot be following backup of a full backup

A

Synthetic Backup

33
Q

what are the two most important storage system technologies

A

file level storage and block
level storage.

34
Q

it block
level storage.is the process of creating raw blocks of storage, which can be
handled individually.

A

block
level storage.

35
Q

This system is commonly used in SAN. It is presented as a hard
disk to the server. The blocks are controlled by the Server based OS.

A

block
level storage.

36
Q

it is the process of backing up entire file system if there
is a slight modification in any of the files

A

File Level Storage

37
Q

This is the most common storage
system that we find with our hard-drives, NAS systems, which is used to
share files with users.

A

File Level Storage

38
Q

They are configured with common file level protocols
such as NTFS (windows) and NFS (Linux)

A

File Level Storage

39
Q

This method is cost effective
when compared to block level storage.

A

File Level Storage

40
Q

A hybrid model using both levels of
storage can also be used based on the requirement of the enterprise.

A

File Level Storage

41
Q

Time period between the disaster occurrence and time where application,
server or business activities are up and running again in their established order can be
defined

A

recovery time objective.

42
Q

When a disaster occurs, time period prior to occurrence of a disaster during which
data is lost and is of allowable, limit can be defined as?

A

recovery point objective.

43
Q

it is measured in days or hours

A

Age of Backup

44
Q

it refers to the time period a backup copy will be retained.

A

Age of Backup

45
Q

Time taken for a backup to be successfully executed and stored

A
  • Time taken to backup
46
Q

Time taken by the server for the recovery of lost data. This depends on
factors such as network speed, size of data, type of network, speed of
the media, etc.

A
  • Time taken to recover
47
Q

the financial estimate of Backup and
DR plan in an enterprise. It includes both capital and operational
expenses

A

Total Cost of Ownership

48
Q

The step-by-step procedure of performing a backup can be defined
in the numbered order.(skip)

A

Back up operation (skip)

49
Q

8 step-by-step procedure of performing a backup can be defined
in the numbered order.

A

1.initiates schedules back up process.
2. retrieval of info from back up catalog
3. load back up media in back up device
4. to sent data to be backed up to storage node
5. sends data and updates back up catalog on server.
6. sends data
7.sends metadata and media information
8.updates back up catalog.

50
Q

6 step-by-step procedure of performing a recovery can be defined in the
numbered order

A
  1. requests for data restore
  2. scans catalog to identify the data that is to be restored and client that will receive data.
  3. load backup media in back up device.
  4. data is read and sent.
  5. sends restores metadata
  6. updates back up catalog
51
Q

it offer built-in features like multi-tenancy,
encryption and compression, which are not offered by tape-based solution.

A

cloud based solutions

52
Q

sometimes susceptible to security worries, because data travels over networks,
subject to hacking

A

cloud based solutions

53
Q

Enterprise need to keep on increasing the size of online
storage according to growth in data

A

Storage space

54
Q

One of the main factors in cloud-based Backup and
DR. It is required for both data transfer and storage operations. It has impact
on recovery timeframe.

A

bandwidth utilization

55
