Insert payloads (fylr restore)

This page describes the process of inserting a local backup of JSON payloads to a target fylr instance

The fylr restore command performs POST requests to the API of the target fylr instance. It iterates over the list of payloads from the manifest.json file.

A basic restore command looks like this:

fylr restore \
  --server '<fylr url>/api/v1' \
  --login root
  --password '<cleartext>' \
  --manifest '<instance folder>/manifest.json' \
  --client-id web-client \
  --client-secret foo \
  --client-token-url '<fylr url>/api/oauth2/token' \
  --chunk 1000 \
  --timeout-min=1 \
  --file-api rput \
  --file-version original \
  --purge # --purge OR --continue

  • --server, --login and --password refer to the target server

  • for the --server parameter, include the HTTP Basic Auth: http://<login>:<password>@<fylr url>/api/v1

  • --chunk defines the batch size of objects in POST requests to api/v1/db

    • if the objects are too big or complex, the requests might take too long and cause a timeout

    • in this case, lower this value and continue restoring with --continue

Parameters

    --file-api=STRING            API used to upload files. Leave empty to not upload files. "put": restore tool uploads files synchronous. "rput": target server loads files from remote URLs. "rput_leave": target server stores remote URLs, no data is copied to storage. "rput" and "rput_leave" are faster, "put" might take long.
    --file-api-access-token=STRING
                                 Use this to pass an access token to fylr backends. This is needed to load files from fylr source instances. It appends the "access_token" query parameter to the remote url of files, and removes the "x-fylr-signature" query parameter.
    --file-version=STRING        Set to version to use for upload. "original" might take long for "put". Use "preview" for test runs.
    --upload-versions            Set to true, to not produce local preview versions, but instead upload the source versions. The upload method is used for versions the same way as for the original.
    --rename-versions=RENAME-VERSIONS,...
                                 Rename versions before uploading. This affects uploaded rights as well as file versions. The versions need to be given in the notation "<cls>.<version>:<new version>", e.g. "image.preview:640px" would replace the "preview" version of image to "640px". If the "<new version>" is omitted, the version is removed.

--manifest

Manifest file that has been created by the backup command.

  • this parameter is mandatory!

  • type: string

--server

API Url of the target instance. The Url must include the API base endpoint, for fylr this is <target url>/api/v1.

  • this parameter is mandatory!

  • type: string

--login

Username of the user in the target instance. It should be a user with root rights or sufficient read rights.

  • this parameter is mandatory!

  • type: string

--password

Password of the user in the target instance.

  • this parameter is mandatory!

  • type: string

--purge

Defines the mode of the restoring (purge or continue).

If this is true, the complete restore starts from the beginning, and the target instance is purged.

The parameters --purge and --continue are mutually exclusive. Not both can be true.

  • type: bool

  • default: false

--continue

Defines the mode of the restoring (purge or continue).

If this is true, the restore continues from the last point in the progress.json file, if a previous restore run was interrupted.

The parameters --purge and --continue are mutually exclusive.

  • type: bool

  • default: false

--base-config

Path to a specific base config file. Defaults to <instance folder>/base_config.json from the backup.

To not upload a base configuration to the target instance, specify --base-config=-

This parameter is not allowed in combination with --continue.

  • type: string

  • default: base_config.json

--datamodel

Path to a specific datamodel file. Defaults to <instance folder>/datamodel.json from the backup.

To not upload a datamodel to the target instance, specify --datamodel=-

This parameter is not allowed in combination with --continue.

Trying to upload a datamodel without --purge will not work, if there is already a datamodel on the target instance!

Only use --datamodel=- if the target instance already has a matching datamodel!

  • type: string

  • default: datamodel.json

--skip-constraints

Skip constraints during restore.

  • type: bool

  • default: false

--include-password

Include user password hashes. If this option is true, the restore tool checks if there is at least one user where a password hash is present. This is done by checking the has_passwords flag in the manifest.json. If this value is false, the restore will stop with an error.

If the source is an easydb5: make sure that the source instance is configured to output the user passwords, and repeat the backup. See https://docs.easydb.de/en/sysadmin/configuration/easydb-server.yml/available-variables/ under include_passwords for the necessary settings in the source instance.

For a fylr source instance this is not necessary, since the password hashes are always returned over the API.

  • type: bool

  • default: false

--include-events

Comma separated list of event types.

Use --include-events=- to skip restoring of events.

If this parameter is unset, all events are restored which have a type that is known in fylr. All other events from the backup are ignored.

  • type: string

  • default: ""

--chunk

The upload batch size for objects to the target instance. Can be used to control the size of the requests. It can be lowered if the requests cause timeouts or network problems.

  • type: int

  • minimum: 1

  • maximum: 1000

  • default: 100

--limit

Set this to a number bigger than 0 to limit the number of objects of each objecttype. This can be used to test or debug to only restore a small sample of the source instance.

  • type: int

  • minimum: 0

  • default: 0

--file-api

Method used to upload files. Leave empty to not upload files.

  • put: restore tool uploads files synchronous.

  • rput: target server loads files from remote URLs.

  • rput_leave: target server stores remote URLs, no data is copied to storage.

rput and rput_leave are faster, put might take long.

  • type: string

--file-api-access-token

Use this to pass an access token to fylr backends. This is needed to load files from fylr source instances. It appends the access_token query parameter to the remote url of files, and removes the x-fylr-signature query parameter.

  • type: string

--file-version

Specify which version of the source asset is used. Default is "original" which might take long for --file-api=put.

Use "preview" for test runs with smaller assets.

  • type: string

  • default: "original"

--upload-versions

Set to true, to not produce local preview versions, but instead upload/link the source versions.

The upload method --file-api is used for versions the same way as for the original file.

  • If put or rput is used, the versions are copied from the source instance, but no versions are produced

  • If rput_leave is used, the versions are linked by URL, and no files are copied to the target instance and no versions are produced

  • type: bool

  • default: false

--rename-versions

Rename versions before uploading. This affects uploaded rights as well as file versions.

The versions need to be given in the notation "<cls>.<version>:<new version>", e.g. "image.preview:640px" would replace the "preview" version of class image to 640px.

If the <new version> part is omitted, the version is removed.

  • type: string

--max-parallel-upload-files

Maximum number of parallel uploads of original files and their versions. Defaults to 4 (0 for bulk). The maximum is 10 (unlimited for bulk).

  • type: int

  • minimum: 0

  • maximum: 10

  • default: 4

--timeout-min

Timeout for connections to target in minutes.

Increase this value if you notice timeouts or related network problems when uploading payloads or files to the target system.

  • type: int

  • minimum: 1

  • default: 10

--upload-ignore-files-with-errors

Set to true to ignore file upload errors and strip objects from them.

  • type: bool

  • default: false

--client-id

If the target instance uses OAuth2 for user authentication, this is the configured Client ID.

  • type: string

--client-secret

If the target instance uses OAuth2 for user authentication, this is the configured Client Secret. Can be kept empty if the instance is public.

  • type: string

--client-token-url

If the target instance uses OAuth2 for user authentication, this is the OAuth2 callback endpoint of the instance.

For fylr this is <source url>/api/oauth2/token.

  • type: string

--insecure

This parameter is available in fylr from version v6.14.0.

Set to true to skip the certificate check for the connection to the target instance.

Only use this option if you can trust the remote server!

  • type: bool

  • default: false

--verbose

Set to true to log debugging info.

  • type: bool

  • default: false

--log-network

Set to true to log the requests and responses.
