Q1: Can a virtual machine be included in two different backup strategies?
A: Can not.
Q2: What is backup archiving
A: Backup archiving is a feature introduced starting from HCI version 6.0.0 that allows backup files to be archived to secondary storage. Each archived backup can be restored, providing dual data protection. However, backup archiving does not support Windows shared directories; it supports virtual storage, NFS, iSCSI, and FC, and cannot archive to the original backup repository. Additionally, the archive and backup repositories cannot be stored in the same storage.
A: The virtual machine supports backups to FC/iSCSI external storage, NFS/NAS storage, and can also back up to local storage and virtual storage.
Q4: Difference between quick backup and CDP backup?
A: Quick backups cannot restore the data between the last backup and the point of failure, meaning there is a risk of data loss during that period. CDP (Continuous Data Protection) backup can be configured to record an I/O every second or every 5 seconds. In the event of a virtual machine failure, CDP backup can restore the virtual machine to its state at the time of the failure. CDP backup can be applied to critical virtual machines, enabling near-instantaneous data recovery in case of failure.
Q5: Difference between full backup and incremental backup ?
A: Full Backup: Refers to a complete copy of all data for a virtual machine at a specific point in time.
Incremental Backup: Refers to backing up the data that has changed since the last full backup.
A: The virtual machine supports backups to FC/iSCSI external storage, NFS/NAS storage(IO log not support NFS/NAS), and can also back up to local storage and virtual storage.
