Field	Description
id	string Required field. Policy ID.
name	string Required field. Policy name.
createdAt	string (date-time) String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
updatedAt	string (date-time) String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
enabled	boolean If this field is true, it means that the policy is enabled.
settings	PolicySettings Set of policy settings
folderId	string ID of the folder that the policy belongs to.

PolicySettings

Set of policy settings

Field	Description
compression	enum (Compression) Required field. Archive compression level. `COMPRESSION_UNSPECIFIED` `NORMAL` `HIGH` `MAX` `OFF`
format	enum (Format) Required field. Format of the Acronis backup archive. `FORMAT_UNSPECIFIED` `VERSION_11`: A legacy backup format used in older versions. It's not recommended to use. `VERSION_12`: A new format recommended in most cases for fast backup and recovery. `AUTO`: Automatic version selection. Will be used version 12 unless the protection plan (policy) appends backups to the ones created by earlier product versions.
multiVolumeSnapshottingEnabled	boolean If true, snapshots of multiple volumes will be taken simultaneously.
preserveFileSecuritySettings	boolean If true, the file security settings will be preserved. Deprecated.
reattempts	RetriesConfiguration Required field. Configuration of retries on recoverable errors during the backup operations like reconnection to destination. No attempts to fix recoverable errors will be made if retry configuration is not set.
silentModeEnabled	boolean If true, a user interaction will be avoided when possible. Equals to false if value is not specified.
splitting	Splitting Required field. Determines the size to split backups on. Splitting is not performed if value is not specified.
vmSnapshotReattempts	RetriesConfiguration Required field. Configuration of retries on errors during the creation of the virtual machine snapshot. No attempts to fix recoverable errors will be made if retry configuration is not set.
vss	VolumeShadowCopyServiceSettings Required field. Settings for the Volume Shadow Copy Service (VSS) provider. If not set, no VSS provider is used.
archive	ArchiveProperties The archive properties.
performanceWindow	PerformanceWindow Required field. Time windows for performance limitations of backup and storage maintenance operations.
retention	Retention Required field. Configuration of backup retention rules.
scheduling	Scheduling Required field. Configuration of the backup schedule.
cbt	enum (ChangedBlockTracking) Required field. A configuration of Changed Block Tracking (CBT). `CHANGED_BLOCK_TRACKING_UNSPECIFIED` `USE_IF_ENABLED` `ENABLE_AND_USE` `DO_NOT_USE`
fastBackupEnabled	boolean If true, determines whether a file has changed by the file size and timestamp. Otherwise, the entire file contents are compared to those stored in the backup.
quiesceSnapshottingEnabled	boolean If true, a quiesced snapshot of the virtual machine will be taken. Deprecated.
fileFilters	FileFilters File filters to specify masks of files to backup or to exclude of backuping
sectorBySector	boolean A sector-by-sector backup of a disk or volume creates a backup copy of all sectors of the disk or volume, including those that do not contain data. Therefore, the size of such a backup copy will be equal to the size of the original disk or volume. This method can be used to back up a disk or volume with an unsupported file system.
validationEnabled	boolean Validation is a time-consuming process, even with incremental or differential backups of small amounts of data. This is because not only the data physically contained in the backup copy is verified, but all data restored when it is selected. This option requires access to previously created backup copies.
lvmSnapshottingEnabled	boolean LVM will be used to create the volume snapshot. If LVM fails to create a snapshot (for example, because there is not enough free space), the software will create the snapshot itself.
