This downloaded json file contains the proper credentials needed for firestore-backup to authenticate.

• -a, --accountCredentials <path> - Google Cloud account credentials JSON file.
• -B, --backupPath <path>- Path to store the backup.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase

• -P, --prettyPrint - JSON backups done with pretty-printing.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --prettyPrint

• -S, --databaseStartPath <path> - The database collection or document path to begin backup.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --databaseStartPath /myCollection/document_3

• -L, --requestCountLimit <number> - The maximum number of requests to be made in parallel.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --requestCountLimit 2

• -E, --excludeCollections <id> - Top level collection id(s) to exclude from backing up.

Note: because of how the command line parsing library works multiple collection ids must be specified as separate parameters.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --excludeCollections myFirstAnnoyingCollection --excludeCollections mySecondAnnoyingCollection

• --excludePattern <regex> - Patterns to match against paths to exclude from the backup. All subpaths of matched paths will also be excluded.

These patterns can support excluding several different sections of trees, e.g.:

• Exclude top level collection: ^/collectionToIgnore
• Exclude sub collections of all documents in a collection: ^/organizations/[^/]*/subcollectionToIgnore
• Exclude sub collections at a given level: ^/[^/]/[^/]/subcollectionToIgnore
• Exclude a particular document: ^/organizations/organizationToIgnore

Note: when combining excludePattern with databaseStartPath, the patterns are tested against the full path of the document off the root of database (with a leading slash).

Note: because of how the command line parsing library works multiple exclude patterns must be specified as separate parameters.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --excludePattern '^/collectionToIgnore' --excludePattern '^/[^/]*/[^/]*/subcollectionToIgnore'

• --batchSize <number - The maximum number of documents to fetch in a single request.

Example:

firestore-backup --accountCredentials path/to/credentials/file.json --backupPath /backups/myDatabase --batchSize 25
