A server administrator is restoring a file server from a full backup taken 7 days ago and incremental backups taken daily. The restoration fails with an error about missing catalog files. What is the most likely cause?

A medium-sized company uses a backup strategy that includes a full backup every Sunday at 2:00 AM and differential backups Monday through Saturday at 2:00 AM. The backups are written to a network-attached storage (NAS) device. On Thursday morning, the company experiences a ransomware attack that encrypts all data on the file server, including the NAS. The administrator needs to restore the file server with minimal data loss. The last successful full backup was from the previous Sunday, and differential backups were successful on Monday, Tuesday, and Wednesday. However, Thursday's differential was not completed because the attack occurred before the scheduled time. The administrator attempts to restore using the Sunday full backup and Thursday's differential, but the restore fails because the differential backup on the NAS is also encrypted. Which of the following is the best course of action?

A small business has a single file server running Windows Server 2019. The server uses two internal SATA drives in a RAID 1 mirror for the operating system and data. The company's backup solution performs a full backup every night to an external USB hard drive, which is stored in the server room. The IT administrator recently noticed that the server's system volume is running low on space and decides to migrate the data to a larger drive. During the migration, the server crashes and will not boot. The administrator attempts to restore from the latest backup but finds that the backup drive is corrupted and cannot be read. The company has no offsite backups. What should the administrator have done to prevent this situation?

A medium-sized company runs an e-commerce platform on a cluster of three physical servers hosting virtual machines. The disaster recovery plan includes daily backups to a remote data center using Veeam Backup & Replication. The company's annual disaster recovery drill is scheduled for next week. During the drill, the IT team plans to simulate a complete site failure by powering off the primary data center. The recovery time objective (RTO) is 4 hours, and the recovery point objective (RPO) is 1 hour. The team successfully restores the VMs at the remote site, but the application experiences significant performance degradation and many transactions fail due to database inconsistency. Investigation reveals that the backup was taken at 2:00 AM, but the failure occurred at 10:00 AM, and the application's database had transactions between 2:00 AM and 10:00 AM that were not captured. What should the IT team do to improve the recovery process?

A large enterprise uses a centralized backup solution with a backup server running Commvault. Backups are stored on a deduplicated disk array and replicated to a secondary site for disaster recovery. The company's security team detects ransomware activity that has encrypted several file servers. The backup administrator checks the backup repository and finds that the backup data is also encrypted because the backup service account had permissions to modify backup files, and the ransomware propagated to the repository. The last known good backup is from two weeks ago, which is too old for the organization's RPO of 24 hours. The backup administrator is under pressure to restore operations quickly. Which of the following should the administrator implement to prevent this from recurring?

A mid-sized e-commerce company experienced a ransomware attack that encrypted all on-premises servers and their locally attached backup storage. The attack occurred on a Friday evening; the company was closed over the weekend. By Monday morning, the IT team discovered the encryption and found a ransom note demanding $500,000 in Bitcoin. The company has a disaster recovery plan that calls for restoring from daily tape backups stored offsite. However, the most recent offsite tape was taken home by a backup operator for the weekend and has not been returned. The tape contains full backups from Wednesday. The IT team has clean installation media and application software available. The company's RPO is 24 hours, and RTO is 48 hours. Management wants to minimize data loss and avoid paying the ransom. Based on this scenario, which of the following should the IT team do to recover the business operations?

A healthcare provider is reviewing its disaster recovery strategy. They have two data centers: one primary in City A and a secondary in City B, 200 miles apart. Currently, they perform daily backups that are replicated to City B each night. In the event of a primary site failure, they can fail over to City B, but there is a 4-hour RTO due to manual processes. Their new RTO target is 2 hours, with an RPO of 15 minutes. The IT team is considering various replication technologies. The provider runs a mix of Windows and Linux servers hosting electronic health records (EHR), PACS imaging, and billing applications. Their current backup scheme is a full backup each night, with transaction logs backed up every 6 hours, but these are not immediately shipped offsite. They have experienced power outages in City A, prompting the review. The IT director is concerned about data consistency and quick recovery. The secondary site currently has sufficient hardware to run all critical applications, but data is only updated nightly. The link between data centers has 100 Mbps bandwidth and 10 ms latency, and upgrading it would cost $50,000. The existing staff can script failover procedures. Which solution best meets the new RPO and RTO while staying within budget?

A large financial services company must comply with federal regulations mandating quarterly disaster recovery tests. Their primary data center in New York hosts all trading applications, and a hot site in Chicago is maintained with real-time data replication via synchronous mirroring. During the last DR test, the IT team successfully failed over network and storage within 8 minutes, meeting the 15-minute RTO for connectivity. However, they encountered a major issue: the hot site's firewalls, intrusion detection systems, and application-level access controls were not configured to match the primary environment. The security team had to manually create firewall rules, update IDS signatures, and reconfigure access policies based on documentation, which took over 4 hours. As a result, the total system readiness exceeded 4.5 hours, causing a significant gap in trading operations. The regulatory auditor noted this deficiency and required a corrective action plan. The company must ensure that the next DR test achieves full operational readiness, including security controls, within the 15-minute RTO. The IT budget is already allocated for the current fiscal year, so large capital expenditures are not possible, but the team can leverage existing tools and automation. Which of the following is the BEST approach to address this issue?

A medium-sized e-commerce company operates three critical servers: a web front-end, a database server, and a file server. Currently, a full backup of all servers is performed every Sunday starting at 11:00 PM and completes in about 6 hours. Differential backups run each weekday at 11:00 PM, taking roughly 2 hours. On a Wednesday at 10:00 AM, a ransomware attack encrypts all data on all servers. The IT team’s incident response plan requires restoration with an RPO of 4 hours and an RTO of 8 hours. The latest clean backup is Tuesday’s differential, resulting in approximately 10 hours of data loss. Future attacks could occur at any time. Management is willing to spend up to $200 per month to improve the backup strategy but cannot afford new hardware or a dedicated hot site. The team needs a solution that reduces both RPO and RTO within budget while maintaining simplicity for a small IT staff of two. Which of the following backup strategies should be implemented to best meet these requirements?

A small law firm relies on a single server that hosts a document management system and email. The server is backed up nightly using differential backups to an external USB hard drive that remains connected to the server. One Monday morning, the office manager finds all files encrypted and a ransom note on the screen. The server’s event logs indicate that the encryption began at 2:00 AM on Saturday. The firm’s offsite backup policy rotates two sets of tapes, and the most recent set was taken offsite on Friday evening and is stored in a bank safe deposit box. The USB backup drive, still attached to the server, shows its files also encrypted. The firm does not have a cloud backup service for the server. The office manager wants to restore operations as quickly as possible with minimal data loss and zero risk of reinfection. What is the BEST course of action?
