Acronis Backup & Recovery 10 Storage NodeThe following are the parameters of Acronis Backup & Recovery 10 Storage Node that can be set by using Acronis Administrative Template. Client Connection Limit Description: Specifies the maximum number of simultaneous connections to the storage node by the agents that perform backup or recovery. Possible values: Any integer number between 1 and 2147483647 Default value: 10 Acronis Backup & Recovery 10 agents connect to the storage node to access its managed vaults during backup or recovery. The Client Connection Limit parameter determines the maximum number of such connections that the storage node can handle simultaneously. When this limit is reached, the storage node will use the backup queue (see the next parameter) for the agents that are awaiting connection. Backup Queue Limit Description: Specifies the maximum number of Acronis Backup & Recovery 10 components in the storage node’s backup queue. Possible values: Any integer number between 1 and 2147483647 Default value: 50 The backup queue is a list of Acronis Backup & Recovery 10 components that are awaiting connection to the storage node or are currently connected to it (see the previous parameter). When the number of components in the backup queue is equal to the value in Backup Queue Limit, and another component tries to establish a connection, the storage node does not put the component in the queue. In this case, the component’s connection to the storage node will fail. If the component is an Acronis Backup & Recovery 10 Agent, the corresponding backup or recovery task will stop with the Failed status. Vault Warnings and Limits Specifies the amount of free space in a vault (both as an absolute value and as a percentage) below which a warning or error is recorded in the log. This parameter contains the following settings: Vault Free Space Warning Limit Description: Specifies the amount of free space in a managed vault, in megabytes, below which a warning is recorded in the storage node’s log. Possible values: Any integer number between 0 and 2147483647 Default value: 200 A vault’s free space is the amount of free space on the medium—such as a disk volume—that stores the vault. When the amount of free space in a vault is equal to the value in Vault Free Space Warning Limit or less, a warning is recorded in the storage node’s log, indicating the vault in question. You can view storage node warnings in the Dashboard. Vault Free Space Warning Percentage Description: Specifies the amount of free space in a managed vault, as a percentage of its total size, below which a warning is recorded in the storage node’s log. Possible values: Any integer number between 0 and 100 Default value: 10 The total size of a vault is the vault’s free space plus the size of all archives that are contained in the vault. For example, suppose that two vaults, Vault A and Vault B, are both stored on a disk volume. Suppose further that the size of the archives in Vault A is 20 GB and the size of the archives in Vault B is 45 GB. If the volume has 5 GB of free space, then the total size of Vault A is 20 GB + 5 GB = 25 GB, and that of Vault B is 45 GB + 5 GB = 50 GB, regardless of the size of the volume. The percentage of free space in a vault is the vault’s free space divided by the vault’s total size. In the previous example, Vault A has 5 GB / 25 GB = 20% of free space, and Vault B has 5 GB / 50 GB = 10% of free space. When the percentage of free space in a vault is equal to the value in Vault Free Space Warning Percentage or less, a warning is recorded in the storage node’s log, indicating the vault in question. You can view storage node warnings in the Dashboard. Note: The parameters Vault Free Space Warning Limit and Vault Free Space Warning Percentage are independent of each other: a warning will be recorded every time that either of the thresholds is reached. Vault Free Space Error Limit Description: Specifies the amount of free space in a managed vault, in megabytes, below which an error is recorded in the storage node’s log and any backup to the vault becomes prohibited. Possible values: Any integer number between 0 and 2147483647 Default value: 50 When the amount of free space in a vault is equal to the value in Vault Free Space Error Limit or less, an error is recorded in the storage node’s log. Backups performed to the vault will keep failing until the vault’s free space is above the limit. Vault Database Free Space Warning Limit Description: Specifies the amount of free space, in megabytes, on the volume containing a managed vault’s database, below which a warning is recorded in the storage node’s log. Possible values: Any integer number between 0 and 2147483647 Default value: 20 If the amount of free space on the volume containing a managed vault’s database is less than the value in Vault Database Free Space Warning Limit, a warning is recorded in the storage node’s log, indicating the vault in question. You can view storage node warnings in the Dashboard. The database is stored on the storage node in a local folder whose name is specified in Database path when creating the vault. Vault Database FreeSpace Error Limit Description: Specifies the amount of free space on the volume containing a managed vault’s database, in megabytes, below which an error is recorded in the storage node’s log and any backup to the vault becomes prohibited. Possible values: Any integer number between 0 and 2147483647 Default value: 10 If the amount of free space on the disk containing a managed vault’s database is less than the value of Vault Database Free Space Error Limit, an error is recorded in the storage node’s log. Backups performed to the vault will keep failing until the amount of free space is above the limit. You can view storage node errors in the Dashboard. The |
