Questa pagina descrive come impostare e gestire le policy di eliminazione temporanea.
Puoi impostare nuovi criteri sui bucket per abilitare l'eliminazione temporanea, nonché
aggiornare e controllare lo stato dei criteri esistenti. Per scoprire come disattivare
l'eliminazione temporanea, consulta Disattivare l'eliminazione temporanea.
Per ottenere le autorizzazioni
necessarie per attivare e gestire le norme di eliminazione temporanea,
chiedi all'amministratore di concederti il
ruolo IAM Storage Admin (roles/storage.admin)
nel bucket o nel progetto che contiene il bucket.
Questo ruolo predefinito contiene
le autorizzazioni necessarie per abilitare e gestire le norme di eliminazione temporanea. Per vedere quali sono esattamente le autorizzazioni richieste, espandi la sezione Autorizzazioni obbligatorie:
Autorizzazioni obbligatorie
Per attivare e gestire i criteri di eliminazione temporanea sono necessarie le seguenti autorizzazioni:
storage.buckets.get
storage.buckets.update
storage.buckets.list (questa autorizzazione è necessaria solo se prevedi di utilizzare la console Google Cloud per eseguire le istruzioni riportate in questa pagina)
Modifica la policy di eliminazione temporanea di un bucket
La nuova durata del periodo di conservazione dell'eliminazione temporanea si applica solo agli oggetti o ai bucket che elimini dopo l'entrata in vigore del criterio di eliminazione temporanea. Gli oggetti eliminati temporaneamente esistenti non sono
interessati dagli aggiornamenti apportati al criterio di eliminazione temporanea e vengono conservati
per la durata in vigore al momento dell'eliminazione.
Segui queste istruzioni per modificare la policy di eliminazione temporanea di un bucket:
Console

To learn how to disable\nsoft delete, see [Disable soft delete](/storage/docs/disable-soft-delete).\n\nTo learn how to list and restore soft-deleted objects, see\n[Use soft-deleted objects](/storage/docs/use-soft-deleted-objects). To learn how to list and restore\nsoft-deleted buckets, see [Use soft-deleted buckets](/storage/docs/use-soft-deleted-buckets).\n\nRequired roles\n--------------\n\n\nTo get the permissions that\nyou need to enable and manage soft delete policies,\n\nask your administrator to grant you the\n\n\n[Storage Admin](/iam/docs/roles-permissions/storage#storage.admin) (`roles/storage.admin`)\nIAM role on the bucket or the project that contains the bucket.\n\n\nThis predefined role contains\n\nthe permissions required to enable and manage soft delete policies. To see the exact permissions that are\nrequired, expand the **Required permissions** section:\n\n\n#### Required permissions\n\nThe following permissions are required to enable and manage soft delete policies:\n\n- `storage.buckets.get`\n- `storage.buckets.update`\n- `storage.buckets.list` (this permission is only required if you plan to use the Google Cloud console to perform the instructions on this page)\n\nFor information about granting roles, see\n[Use IAM with buckets](/storage/docs/access-control/using-iam-permissions#bucket-iam) or [Manage access to projects](/iam/docs/granting-changing-revoking-access).\n\nEdit a bucket's soft delete policy\n----------------------------------\n\nThe new soft delete retention duration only\napplies to objects or buckets that you delete after the\nsoft delete policy takes effect. Existing soft-deleted objects aren't\naffected by updates made to the soft delete policy and are retained\nfor the duration that was in effect when they were deleted.\n\nUse the following instructions to edit a bucket's soft delete\npolicy: \n\n### Console\n\n1. In the Google Cloud console, go to the Cloud Storage **Buckets** page. \n\n [Go to Buckets](https://console.cloud.google.com/storage/browser)\n2. In the list of buckets, click the name of the bucket whose\n soft delete policy you want to edit.\n\n3. Click the **Protection** tab.\n\n4. In the **Soft delete policy (for data recovery)** section, add a new\n soft delete policy or edit the [retention duration](/storage/docs/soft-delete#retention-duration) of\n an existing policy by using the following steps:\n\n 1. Click **Edit**.\n\n 2. In the **Set a soft delete policy** dialogue that appears, specify\n a [soft delete retention duration](/storage/docs/soft-delete#retention-duration) by choosing a unit\n of time and a length of time.\n\n 3. Click **Save**.\n\nTo learn how to get detailed error information about failed Cloud Storage\noperations in the Google Cloud console, see\n[Troubleshooting](/storage/docs/troubleshooting#trouble-console).\n\n### Command line\n\nTo add or edit the soft delete policy on a bucket, use the\n[`gcloud storage buckets update`](/sdk/gcloud/reference/storage/buckets#update) command with the\n`--soft-delete-duration` flag: \n\n```\n gcloud storage buckets update gs://BUCKET_NAME --soft-delete-duration=SOFT_DELETE_DURATION\n```\n\nWhere:\n\n- \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the bucket. For\n example, `my-bucket`.\n\n- \u003cvar translate=\"no\"\u003eSOFT_DELETE_DURATION\u003c/var\u003e specifies the\n [soft delete retention duration](/storage/docs/soft-delete#retention-duration).\n\n - The unit `s` represents seconds.\n - The unit `d` represents days.\n - The unit `m` represents months.\n\n For example:\n - `7d43200s` sets a retention duration of seven and a half days\n (7 days and 43,200 seconds).\n\n - `2w1d` sets a retention duration of two weeks and one day.\n\n### REST APIs\n\n### JSON API\n\n1. Have gcloud CLI [installed and initialized](/sdk/docs/install), which lets\n you generate an access token for the `Authorization` header.\n\n\n2. Create a JSON file that contains the following information:\n\n\n ```json\n {\n \"softDeletePolicy\": {\n \"retentionDurationSeconds\": \"\u003cvar translate=\"no\"\u003eTIME_IN_SECONDS\u003c/var\u003e\"\n }\n }\n ```\n\n\n Where \u003cvar translate=\"no\"\u003eTIME_IN_SECONDS\u003c/var\u003e is the amount of\n time in seconds you want to set the\n [soft delete retention duration](/storage/docs/soft-delete#retention-duration) to. For\n example, `2678400` for 2,678,400 seconds (31 days).\n3. Use [`cURL`](http://curl.haxx.se/) to call the [JSON API](/storage/docs/json_api) with a\n [`PATCH` Bucket](/storage/docs/json_api/v1/buckets/patch) request:\n\n ```\n curl -X PATCH --data-binary @JSON_FILE_NAME \\\n -H \"Authorization: Bearer $(gcloud auth print-access-token)\" \\\n -H \"Content-Type: application/json\" \\\n \"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME\"\n ```\n\n Where:\n - \u003cvar translate=\"no\"\u003eJSON_FILE_NAME\u003c/var\u003e is the path for the JSON file that you created in Step 2.\n - \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the relevant bucket. For example, `my-bucket`.\n\nCheck if the soft delete policy is enabled on a bucket\n------------------------------------------------------\n\n### Console\n\n1. In the Google Cloud console, go to the Cloud Storage **Buckets** page. \n\n [Go to Buckets](https://console.cloud.google.com/storage/browser)\n2. In the list of buckets, click the name of the bucket whose\n soft delete policy you want to check.\n\n3. Click the **Protection** tab.\n\n The status displays in the **Soft delete policy (for data recovery)**\n section.\n\nYou can also use the **Protection tab** to check if there's a\nsoft delete policy on your bucket.\n\nTo learn how to get detailed error information about failed Cloud Storage\noperations in the Google Cloud console, see\n[Troubleshooting](/storage/docs/troubleshooting#trouble-console).\n\n### Command line\n\nTo check the soft delete policy status of a bucket, use the\n[`gcloud storage buckets describe`](/sdk/gcloud/reference/storage/buckets/describe) command: \n\n```\n gcloud storage buckets describe gs://BUCKET_NAME \\\n --format=\"default(soft_delete_policy)\"\n```\n\nWhere:\n\n- \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the bucket. For example, `my-bucket`.\n\n### REST APIs\n\n### JSON API\n\n1. Have gcloud CLI [installed and initialized](/sdk/docs/install), which lets\n you generate an access token for the `Authorization` header.\n\n\n2.\n\n Use [`cURL`](http://curl.haxx.se/) to call the [JSON API](/storage/docs/json_api) with a\n [`GET` Bucket](/storage/docs/json_api/v1/buckets/get) request: \n\n ```\n curl -X GET \\\n -H \"Authorization: Bearer $(gcloud auth print-access-token)\" \\\n -H \"Content-Type: application/json\" \\\n \"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME?fields=softDeletePolicy\"\n ```\n\n Where \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e is the name of the\n relevant bucket.
