cbbackupmgr info

Return information about the backup archive

SYNOPSIS

cbbackupmgr info [--archive <archive_dir>] [--repo <repo_name>]
                 [--backup <bucket_list>] [--bucket <bucket>]
                 [--json] [--all]

DESCRIPTION

(NOTE): This command is in developer preview.

This command provides information about the given path, be it the whole archive, repository, backup or bucket. The information can be displayed in a tabular format or JSON. By default only two levels of the data hierarchy will be displayed in tabular format, to see it all use the --all flag. For the exact format of the output please see the examples below. Unlike the list command this command will not list individual files.

OPTIONS

Below are the required and optional parameters for the info command.

Required

-a,--archive <archive_dir>: The location of the backup archive to display information about.

Optional

-r,--repo <repo_name>: If specified, the info command will only display information for this backup repository.
--backup <backup>: If specified, the info command will only display information for this backup. The --repo flag must also be specified if this flag is used.
--bucket <bucket>: If specified, the info command will only display information for this bucket. The --repo and --backup flags must also be specified if this flag is used.
--json: If specified the output will be a json object.
--all: Show all levels of the data hierarchy. Note that for json output all levels are always returned.

EXAMPLES

The info command will display information of the backup archive in a user friendly manner. Let’s imagine we have a backup archive /backup_archive and we want to see information about it we would run the command:

$ cbbackupmgr info -a /backup_archive

Name             | Size      | # Repos  |
backup_archive   | 111.00MB  | 2        |

*    Name        | Size     | # Backups  |
*    Manchester  | 55.56MB  | 1          |
*    London      | 55.44MB  | 2          |

This shows us that the archive backup_archive has two repositories and has a total size of 110MB. It will also provide one level more into the hierarchy and show information of the two repositories Manchester and London and we can see their respective sizes as well as the number of backups each contains.

If we wanted to get more in depth information of the repository we would provide the repository name as follows:

$cbbackupmgr info -a ~/backup_archive -r London

Name    | Size     | # Backups  |
London  | 55.44MB  | 2          |

+  Backup                       | Size     | Type  | Source                 | Range  | Events  | Aliases  | Complete  |
+  2019-03-15T13_19_54.826458Z  | 3.02MB   | INCR  | http://localhost:8091  | N/A    | 0       | 1        | true      |
+  2019-03-15T12_18_00.514284Z  | 52.42MB  | FULL  | http://localhost:8091  | N/A    | 0       | 1        | true      |

This gives more in depth information about each backup such as the timestamp from when it was made, the size, the type which can be either a full backup (FULL), and incremental backup (INCR) or a merge (MERGE). We can also see the address of the cluster we backed up the data from. The range column is used by merges. If the backup is a merge the range has the start timestamp the end timestamp and the number of backups that where merge in the format start - end : count. Event and aliases are the number of events and full text search indexes aliases that where restored. Finally the complete field indicates if the backup finished successfully or not.

It is possible to get information for an individual backup as well by using the following command:

$ cbbackupmgr info -a ~/backup_archive -r London --backup 2019-03-15T12_18_00.514284Z

Backup                       | Size     | Type  | Source                 | Range  | Events  | Aliases  | Complete  |
2019-03-15T12_18_00.514284Z  | 52.42MB  | FULL  | http://localhost:8091  | N/A    | 0       | 1        | true      |

 -   Bucket          | Size     | Items  | Mutations | Tombstones | Views  | FTS  | Indexes  | CBAS  |
 -   beer-sample     | 6.85MB   | 7303   | 7303      | 0          | 1      | 0    | 1        | 0     |
 -   gamesim-sample  | 2.86MB   | 586    | 586       | 0          | 1      | 0    | 1        | 0     |
 -   travel-sample   | 42.72MB  | 31591  | 31591     | 0          | 0      | 0    | 10       | 0     |

The command above provides information about all buckets in the specific backup. This includes the size of the data in each bucket, the number of items which includes mutations and tombstones, the number of mutations and the number of deletions. For backups made with cbbackupmgr older than 6.5 mutations and deletions will always be 0 as this is only supported by archives made with cbbcakupmgr 6.5+. For the buckets it will also shows the number of view, full text indexes, the number of GSIs and the number of analytics metadata records.

To see information for one bucket only we would use the --bucket flag and give it the name of the bucket and this would return just the information for that bucket.

To see from one level to the last the --all flag must be provided this will show the information from the provided level to the bucket level. An example can be seen below:

$ cbbackupmgr info -a ~/backup_archive --all

Name         | Size     | # Repos  |
backup_repo  | 55.56MB  | 1        |

*  Name        | Size     | # Backups  |
*  Manchester  | 55.56MB  | 1          |

+    Backup                      | Size     | Type   | Source  | Range                                      | Events  | Aliases  | Complete  |

-      Bucket          | Size     | Items  | Mutations | Tombstones | Views  | FTS  | Indexes  | CBAS  |
-      beer-sample     | 6.85MB   | 7303   | 7303      | 0          | 1      | 0    | 1        | 0     |
-      gamesim-sample  | 2.86MB   | 586    | 586       | 0          | 1      | 0    | 1        | 0     |

The info command also allows for JSON output which can be useful for automation or users that would rather get the information in json format. The output json will have the format seen below. Note that all sizes will be in bytes and that for non-merge backups the range field will be empty.

  “name”: NAME,
  “size”: SIZE,
  “repos”: [
    {
      “name”: NAME,
      “size”: SIZE,
