Purpose

This article documents how to customize the retention options that are available when configuring the following tasks:

Copy Backup

Export Backup

VeeamZIP

Solution

The custom retention options are loaded by the Veeam Backup Service during startup of the service.

Custom retention options may be configured using the following file:

C:\Program Files\Veeam\Backup and Replication\Backup\Config\Retention\AutodeleteRetention.json

Default File Contents:

{
  "options": [
    {
      "name": "1 week",
      "period": 7,
      "unit": "days"
    },
    {
      "name": "2 weeks",
      "period": 14,
      "unit": "days"
    },
    {
      "name": "1 month",
      "period": 1,
      "unit": "months"
    },
    {
      "name": "3 months",
      "period": 3,
      "unit": "months"
    },
    {
      "name": "6 months",
      "period": 6,
      "unit": "months"
    },
    {
      "name": "1 year",
      "period": 1,
      "unit": "years"
    },
    {
      "name": "2 years",
      "period": 2,
      "unit": "years"
    },
    {
      "name": "3 years",
      "period": 3,
      "unit": "years"
    },
    {
      "name": "5 years",
      "period": 5,
      "unit": "years"
    },
    {
      "name": "7 years",
      "period": 7,
      "unit": "years"
    }
  ]
}
                
            

Notes:

The final value between curly brackets { } does not have a comma (compare line# 52 to line# 47).

If the AutodeleteRetention.json file contains invalid data, Veeam Backup & Replication will default to the embedded default settings. An error regarding the parsing failure will be recorded in C:\ProgramData\Veeam\Backup\Svc.VeeamBackup.log
For example:

Info (3)    [CAutodeleteRetentionOptionsProvider] Loading config from file C:\Program Files\Veeam\Backup and Replication\Backup\Config\Retention\AutodeleteRetention.json
Info (3)    [CAutodeleteRetentionConfigParser] Parsing autodelete retention config
Error (3)    [CAutodeleteRetentionOptionsProvider] Could not load retention config from file
Error (3)    After parsing a value an unexpected character was encountered: {. Path 'options[1]', line 13, position 4. (Newtonsoft.Json.JsonReaderException)
Info (3)    [CAutodeleteRetentionOptionsProvider] Loading embedded config
Info (3)    [CAutodeleteRetentionConfigParser] Parsing autodelete retention config
Info (3)    [CAutodeleteRetentionOptionsProvider] Embedded config successfully loaded

Take note of the last line in the example above; if the AutodeleteRetention.json is correctly parsed and loaded, this line will read:

Info (3)    [CAutodeleteRetentionOptionsProvider] Config from file successfully loaded

Consider using a JSON validator, like https://jsonlint.com/

If the AutodeleteRetention.json file has been loaded correctly, the custom values will appear in the UI, and the following entries will be found in the "C:\ProgramData\Veeam\Backup\Svc.VeeamBackup.log" log file:

Info (3)    [CAutodeleteRetentionOptionsProvider] Loading config from file C:\Program Files\Veeam\Backup and Replication\Backup\Config\Retention\AutodeleteRetention.json
Info (3)    [CAutodeleteRetentionConfigParser] Parsing autodelete retention config
Info (3)    [CAutodeleteRetentionOptionsProvider] Config from file successfully loaded

More Information

The custom retention settings selection only affects the retention of items at the time they are created. Changes to the AutodeleteRetention.json file will not affect the retention of items that have already been copied, exported, or created.
