Workstation Backup and Recovery Methods Flashcards
Full Back-up
Complete data sets.
First step for all backup types.
Fast restore time.
Start.
Time consuming.
Greatest storage accrual.
Excessive consumption.
Incremental Back-up
Partial data sets.
Copies all data from last full or incremental backup.
Fastest backup times.
Least storage accrual.
Lowest bandwidth consumption.
Slowest restore time.
Most common.
Differential Back-up
Gradually increasing data sets.
Middle ground approach.
Lower storage, time, and bandwidth consumption than full backups.
Synthetic Back-up
-Creates complete data set by combining (synthesizing) sets with an original complete data set.
-Utilizes the incremental data types.
-Doesn’t require storing full backups twice.
-Offers benefits of incremental backup type.
Backup testing, frequency, and rotation schemes
- On site versus off site.
- Grandfather-father-son (GFS)–Grandfather: A full backup of the data at the beginning of the year
Father: A full backup of the data at the beginning of the month
Son: A full backup and increments of the data once a week - 3-2-1 backup rule–a data protection strategy that recommends keeping three copies of your data on two different devices, with one copy stored off-site
