Backup subsystem statistics

Attribute

Description

Aborted Backups

Total number of times backups have been aborted.

Backup In Progress

If a backup is in progress, this counter is set to 1. Otherwise, this counter is set to 0.

Backups Started

Total number of backups that have been started.

Backups Started non-Component

Total number of VSS, non-component mode backups that have been started. For example, a backup with NtBackup.exe will cause this counter to be incremented.

Backups Started non-VSS

Total number of non-VSS backups that have been started.

Failed Backups

Total number of backups that have failed.

Last Backup Copy Failures

Number of file copy failures from the last backup. This counter is not incremented for a non-component mode backup.

Last Backup Duration

Time in seconds of last backup.

Last Backup Failed

If the last backup failed or if the last backup was aborted or if the last backup's verification check failed, this counter will be 1. Otherwise, this counter is set to 0.

Last Backup Files Copied

Number of files copied in last backup. This counter is not incremented for a non-component mode backup.

Last Backup Files Skipped

Number of files not copied in last backup because a file of the same last modified date and size already exists in the destination. File copies can be skipped for incremental, differential, and full backups. This counter is not incremented for a non-component mode backup.

Last Backup Init Duration

Initialization duration. The number of seconds required to start backup after the backup was requested. This should typically be 0 for non-VSS backups and about 5 seconds or less for VSS backups.

Last Backup Megabytes Copied

Number of megabytes copied in last backup. This counter is not incremented for a non-component mode backup.

Last Backup PrepareBackup To Freeze Duration

Number of seconds between PrepareBackup and Freeze events. This can be a long time for a non-VSS backup if the backup is waiting for an archive shift to complete.

Last Backup Total File Count

Total files identified for last backup. Should be equal to copied + skipped + failed unless the backup is non-component mode.

Last VSS Freeze Duration

Time in milliseconds between start of the freeze event and the end of the thaw event for the last VSS backup.

Last VSS Freeze Transition

Time in milliseconds to acquire exclusive write locks in all subsystems participating in backup.

Verification Failures

Total number of verification failures.
