LP - Resiliance and Recovery Flashcards
Full and incremental backups do what to the archive bit
set it to zero
What do Differential Backups do to the archive bit?
Nothing, it does not change it
Differential backup any
new file or any file that has changed since the last full backup
Differential backups need what to restore files?
The last full and differential backup
Snapshots are immediate point-in-time
virtual copies of the source data
Snapshots offer improved
RTO and RPO
Snapshots are faster or slow to backup

Backup frequency for full backups
at least weekly

What is journaling?
It is the simultaneous (real-time) logging of all data-files updates.
What does journaling offer?
an audit trail and is used to reconstruct the database if the original is damaged or destroyed
TDE stands for
Transparent database encryption
EKM stands for
Extensible key management
KMS stands for
Cloud-based key management service
COOP is the same as
BCP
COOP stands for
continuity of operations
BCP stands for
business continuity plan
The three main components of a BCP are
BIA, DRP, BU/R
BIA stands for
business Impact Analysis
DRP stnads for
disaster recovery planning
BU/R stands for
backup and restore policy
The steps from NIST SP 800-34, Revision 1
- Develop a continuity planning
- Conduct the business impact analysis (BIA)
- Identify preventive controls
- Create contingency stratefies
- Develop an information system contingency plan
- Ensure plan testing, training and exercises
- Generate after-action report
- Esoons learned and ongoing plan maintenance
Business impact analysis (BIA) key objectives are:
RTO
MTD (maximum tolerable downtime)
RPO
MTTR
MTBF
The RTO must be less than or equa to the
MTD
Generators should heave enought fuel for how many hours of operation
