![]() ![]() msi file for the product build that you use:Ģ. No direct SAN access backup support (since there is no Windows Agent – only appliance).ġ.The agent has to be deployed manually from.msi file, and can be imported to an ESXi host as an OVF template. ![]() ![]() The 64-bit Agent for VMware (Virtual Appliance) is designed for VMware vSphere 6.5 and 6.7. If Exchange server reboot is part of maintenance operations, the next successful backup will be a regular express full backup.Starting with Acronis Backup 11.7 Update 1 HF4, vSphere 6.5 and 6.7 are suported. What happens when maintenance operations involve rebooting of the Exchange server? If one or more of the scheduled express full backups fail, the next successful backup will be a regular express full backup based on differences since the previous successful backup. What if one of the scheduled backups fails? The next backups after the "re-synced" backup will proceed as regular express full backups. Although the re-sync increases the number of I/O requests to the production server, it still saves storage space and network traffic. At the next backup, Acronis Backup runs the data re-sync backup operation by comparing the current database files with the most recent backup rather than performing a regular full database backup. What happens in case of an unexpected system shutdown?Īn unexpected system shutdown between the express full backups invalidates information maintained by the Express Backup Driver. After that, deduplication at target is performed in the same way as for disk-level and file-level backups. Since the unchanged data is already stored in the deduplicating vault, the agent only adds links to this data. The agent transfers only the changes and the data that cannot be deduplicated (transaction log files and database page headers). The driver determines the offsets and regions of the database file modified by Exchange and stores information about these modifications in the list of changed file regions.Īt the next backup, the driver provides the list to the agent and the agent starts to back up only the data corresponding to this list. The express full backup method is based on monitoring Exchange database files performed by Acronis Express Backup Driver.īeginning from the first regular full backup, the driver monitors all modifications performed on the database file. ![]()
