Repository and Storage Management Flashcards

A Veeam administrator wants to move a backup repository extent out of a Scale-out Backup Repository without losing any backup data. What is the correct procedure?

Answer: Switch the extent to maintenance mode, evacuate backups to other extents, then remove it from the SOBR

Placing the extent into maintenance mode triggers automatic evacuation of backup files to other extents in the SOBR before the extent can be safely removed.

Which Veeam technology allows a Linux repository to serve as both a backup target and as a secure, air-gapped immutable storage location without requiring a separate appliance?

Answer: Veeam hardened repository using Linux immutable flag (chattr +i)

The Veeam hardened repository uses Linux's native immutable file attribute (chattr +i) to prevent modification or deletion of backup files for a configurable period, turning a commodity Linux server into an immutable storage target.

When Veeam performs a health check on a backup repository, what operation does it carry out?

Answer: It reads and CRC-validates all data blocks in the most recent restore point against stored checksums

The health check reads backup data blocks and validates them against stored CRC checksums to detect silent data corruption without performing a full restore.

What is the recommended action when a Veeam administrator receives a 'Repository does not have enough free disk space' warning but no backup jobs have failed yet?

Answer: Expand repository capacity, reduce retention settings, or add a new extent to the SOBR before space is exhausted

The warning indicates that space is running low; proactive steps—adding storage, adding extents, or reducing retention—should be taken before jobs start failing.

Which Veeam backup repository configuration is best suited for a remote office with limited WAN bandwidth that must store backups locally and replicate only changed blocks to headquarters?

Answer: A local repository managed by Veeam Backup & Replication at the remote site with a Backup Copy job using WAN Acceleration

WAN Accelerator technology in Veeam Backup Copy jobs caches and deduplicates data on both ends, significantly reducing the amount of data sent across limited WAN links.

In Veeam's immutability model for a hardened Linux repository, what occurs when the immutability period expires for a backup file?

Answer: The file's immutable flag is cleared and Veeam can then delete it according to normal retention rules

Once the immutability period expires, Veeam removes the chattr +i flag, after which standard retention processing can delete the file as scheduled.

A Veeam repository is configured with a 30-day retention policy. A backup administrator enables GFS (Grandfather-Father-Son) retention on the same job. How do the two retention settings interact?

Answer: GFS restore points are kept beyond the 30-day rolling retention, while non-GFS restore points still follow the 30-day limit

GFS flags mark specific restore points (weekly, monthly, yearly) to be retained longer than the standard rolling retention period, so those flagged points survive past the 30-day window.
