Creating an incremental backup job
Incremental backups can be modified with the following operations:
• Active Block Mapping (ABM): ABM scans the disks on a VM and detects the blocks actively used by the disk, as opposed to blocks that were deleted by the Windows® operating system. With ABM enabled, vRanger only backs up the part of a virtual disk that has active data on it. ABM also provides the following settings options:
• Changed Block Tracking (CBT): CBT reduces the time needed for incremental and differential backups by only backing up the portions of a disk that have changed since the last backup. By determining which blocks changed within the VMDK file, vRanger only backs up the portions of a disk that have changed since the last backup. This often results in shorter durations for backup operations, and reduced resource consumption on network and storage elements.
NOTE: CBT does copy deleted blocks if ABM is not also enabled. CBT is a VMware® feature, and does not apply to physical machine or Hyper-V® VM backup.For more information about selecting the ABM and CBT operations, see Configuring backup options.
To create an incremental backup job:
1 On the Retention Policy Selection page, select your Savepoint Count — the default setting is 7, the maximum value is 1000.
2The Options section appears.
▪ Threshold Count: This option defines the number of incremental backups to perform before a full backup is done.Use the up and down arrows to select a threshold count — the default is 6.
▪ Full Backup Days: Select the day or days on which you want vRanger to take a full backup of the server.

Creating a differential backup job
Differential backups can be modified with the following operations:
• Active Block Mapping (ABM): ABM scans the disks on a VM and detects the blocks actively used by the disk, as opposed to blocks that were deleted by the Windows® operating system. With ABM enabled, vRanger only backs up the part of a virtual disk that has active data on it. ABM also provides the following settings options:
• Changed Block Tracking (CBT): CBT reduces the time needed for incremental and differential backups by only backing up the portions of a disk that have changed since the last backup. By determining which blocks changed within the VMDK file, vRanger only backs up the portions of a disk that have changed since the last backup. This often results in shorter durations for backup operations, and reduced resource consumption on network and storage elements.
NOTE: CBT copies deleted blocks if ABM is not also enabled. CBT is a VMware® feature, and does not apply to physical machine or Hyper-V® VM backup.For more information about selecting the ABM and CBT operations, see Configuring backup options.

▪ Threshold Count: This option defines the number of incremental backups to perform before a full backup is done.Use the up and down arrows to select a threshold count — the value is 6.
▪ Full Backup Days: Select the day or days on which you want vRanger to take a full backup of the server.
▪ The Threshold Size refers to the percentage of the hard disk of a VM that must be captured in differential backups before performing a full backup. Using the Threshold Size value might cause your full backups to be taken on unexpected days.

Setting the recurrence schedule
To set the recurrence schedule:
1 On the Recurrence Schedule Selection page, select from the options described in the following table.
There is no need to define a schedule. The job runs on demand.
• Daily: The daily option can be scheduled to run the report every weekday or every x number of days.
• Weekly: vRanger can be configured to run on weekly intervals, from every week to every 99 weeks. The day of the week on which to run reports can be configured.
• Monthly: The monthly option offers the following configurations:
▪x can be any value from 1 to 31. This value determines the day of the month on which the job occurs.
y can be any value from 1 to 99. This value determines the monthly interval — for example, every two months sets the job to run every other month.
▪f can be either: first, second, third, fourth or last.
d can be: weekday, weekend day, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.
y can be any value from 1 to 99. This value determines the monthly interval — for example, every two months sets the report to run every other month.
• Yearly: The yearly option offers the following configurations:
▪ Every [m] [x]:m is any month of the year. This value determines the month of the year in which the report occurs.
x can be any value from 1 to 31. This value determines the day of the month on which the report occurs.
▪f can be either: first, second, third, fourth, or last.
d can be: day, weekday, weekend day, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.
m is any month of the year. This value determines the month of the year in which the report occurs.
• Interval: The interval option lets you select the number of days, hours, and minutes that should pass between backup jobs.Select the starting date and ending date:
• No end date: The job recurs until it is stopped.
• End after: Select the number of occurrences.
• End by: Select the date by which to end the recurrence.
