Problem
After completing backups, need to understand files related to Incremental and Full backups.
Solution
.v2i - Base or Full Backup recovery point image. This can be created from a baseline or Independent Backup.
.iv2i - Incremental image. An incremental includes changes since the last incremental was performed or since the BASE.
.sv2i - System Restore File. Each time a backup image is created, a system index file is saved along with it.
The system index file (.sv2i) is created when a backup operation is performed that has multiple drives or a recovery point set (base and incremental backups). A system index file reduces the amount of time that is needed to restore the drives. When a recovery point is created, a system index file is saved with it. The system index file contains a list of the most recent recovery points, which includes the original drive location of each recovery point.
.fbf - File Folder Backups.
Recovery Point Set definition: A recovery point set is defined as the Base + all incrementals associated with that Base.
- For example: if you create a Base backup on the first of each month and incrementals once per week, you will have 5 backup images (one base and 4 incrementals) at the end of the month. All 5 of these images comprise one recovery point set.
· Recovery Point Set Example:
C_Drive001.v2i (Base backup for recovery point set #1)
C_Drive001_i001.iv2i (incremental backup #1 for recovery point set #1)
C_Drive001_i002.iv2i (Incremental backup #2 for recovery point set #1)
C_Drive002.v2i (Base backup for recovery point set #2)
C_Drive002_i001.iv2i (Incremental backup #1 for recovery point set #2)
By default, scheduled independent recovery point file names and recovery point
set file names are appended with 001.v2i, 002.v2i, and so forth.
Incremental recovery point file names within a set are appended with _i001.iv2i, _i002.iv2i,
and so forth. For example, if your base recovery point is called Server001.v2i,
the first incremental recovery point is called Server 001_i001.iv2i.
