Importing/exporting a storage definition

Vidispine can export a definition document describing all the files within a storage, which can later be imported to a new storage on a different Vidispine instance.

Export a storage definition

GET /storage/(storage-id)/export

Role:

_storage_read

Import a storage definition

POST /storage/import

Creates a new storage based on the StorageImportDocument. A file entity will be created for each entry in the document, if a file with that ID does not already exist. Finally, a storage method will be added, with the path supplied in the call.

Query Parameters:
 
  • path (string) – The file system path to where the files are located.
Accepts:
Role:

_storage_write

Evacuating storages

If you would like to delete a storage, but you still have files there which are connected to items, you can first trigger an evacuation of the storage. This will cause Vidispine to attempt to delete redundant files, or move files to other storages. Once the evacuation is complete, the storage will get the state EVACUATED.

Evacuate a storage

PUT /storage/(storage-id)/evacuate

Trigger evacuation of a storage.

Role:_storage_write

Cancel evacuation of a storage

DELETE /storage/(storage-id)/evacuate

Cancel the evacuation process on a storage.

Role:_storage_write

Key-value metadata

Storages support key-value metadata.

Reserved keys

Certain keys are used to control the behavior of a storage, they must not be used to store generic metadata.

closeLimit

An integer specifying the number of minutes until the system automatically considers an open file to be closed.

Default:5
lostLimit

An integer specifying the number of minutes until the system automatically considers a missing file to be lost.

Default:10
toAppearLimit

An integer specifying the number of minutes the system waits for a file to appear before considering it to be missing.

Default:10
refreshInterval

The interval (in seconds) that Vidispine will compare the list of file seen on disk with the list of files in the database. This to fix any possible mismatch.

Default:900
hashMode

Set to false to disable hash computation for this storage.

Default:true
additionalHash

A comma-separated list of additional hashing algorithms that should be applied to files. E.g.: MD5,SHA-256.

The hash algorithm FILENAME is also supported, which takes the last part of the path concatenated with the file size, and calculates a SHA-1 checksum of that string.

Default:(none)
fileListBatchSize

Maximum size of list of files that are updated in the database at the same time.

Default:100000
keepMissingFiles

If set to false then missing files that do not belong to any items will be removed from the database instead of being marked as lost.

Default:To the value of the configuration property keepMissingFiles.
keepEmptyDirectories

Do not delete empty parent directories when deleting the last file in a directory, see Parent directory management.

Default:To the value of the configuration property keepEmptyDirectories.
statsPerSecond

An integer specifying the maximum number of stat system calls that are made to the storage (only file:// URIs). See also the configuration property statsPerSecond.

Default:(none)
scanOnStart

By default, Vidispine will scan the file system on start-up. Storages that should never be scanned, that should solely use SQS or SNS for example, should have this parameter set to false.

Default:true
Since:5.0
refreshOnStart

By default, Vidispine synchronizes the database with the file system on start-up. On very large systems, this can take a very long time. Set this parameter to false, and use the rescan functionality (see below) instead.

Default:true
deleteFileIfNotFound

If set to true: if file that is marked for deletion cannot be deleted, but is not found on the file system, it is assumed to be deleted.

Default:false
deleteFileIfReadOnly

If a file that is marked for deletion cannot be deleted, and the file exists on a read-only storage, then:

  • If set to true: delete the file from the database, as if the file had been deleted.
  • If set to a file state: set the file to this state.
Default:false
Example:true, ARCHIVED, LOST
excludeFilter

A regular expression. Any file with a path (relative to the storage’s root folder) that matches the expression will be ignored. Note that the expression must match the entire path, not only a part of the path.

Default:(none)
detectRenamedFiles

If this metadata is set to true, whenever a file belonging to an item is marked as LOST, and there is another file on the same storage with the same hash value, the new file is associated with the item instead.

Other possible values are all, where the old (lost) file resided on any storage, or a comma-separated list of identifiers of storages on which the old (lost) file resided on.

Default:(none)
probeFileBeforeClosing

If this metadata is set to true, Vidispine will attempt to read OPEN files before marking them as CLOSED. This is useful for Windows storages where the metadata is constant while a file is copied to the storage, but the file cannot be read (file is busy).

Default:false
vxaId

If this metadata field is set, the storage will be automatically deleted if the share is removed from the Vidispine Server Agent.

Default:(none) for regular storages, automatically set by VSA when a share is added and a storage is created.
sqsName

The name of Amazon SQS queue to poll for S3 file events. See S3 Event SQS Notifications for more information.

This key is only read for S3 methods.

sqsEndpoint

The endpoint of Amazon SQS queue.

This key is only read for S3 methods.

Example: sqs.eu-west-1.amazonaws.com

snsTopic

The ARN of an SNS topic to receive S3 file events from. See S3 Event SNS Notifications for more information.

Example:arn:aws:sns:eu-west-1:123456791011:topic_name
s3EventETag

When receiving file events from SNS this can be specified to set the ETag included in the message from the storage as metadata on the file.

Example:true
Default:false
s3EventTime

When receiving file events from SNS this can be specified to set the timestamp in the message received as metadata on the file.

Example:true
Default:false
hashingThreadCount

The number of hashing thread that should be run on the VSA side. Note: this configuration only work for VSA storage.

Default:1
noDefaultHash

Do not calculate hash checksums for files on the storage.

Example: true

Default:false
verifyHashAfterTransfer

If a job is copying or moving a file to this storage the hash of the source file and the hash of the newly copied/moved file are compared to ensure that the new file is binary identical to the original file. If the hashes differ the job fails and the destination file is removed.

  • If set to true: hash verification is performed after the file has arrived on this storage.
  • If set to false: no hash verification is performed.

The hash verification procedure makes use of the hash calculation that is happening on all storages by default (see File hashing). If hash calculation is disabled on the source storage the hash is calculated before the copy/move operation is performed. If hash calculation is disabled on the destination storage the hash is calculated after the copy/move operation has completed. These hashes are stored in the Vidispine database for later reuse.

Note that hash calculation requires reading the whole file and thus is a lengthy process that can significantly increase execution time of copy/move jobs.

Default:false
storageActivationFile

Require a .storage file to be present in the storage method’s URI for storage to register as online. Takes precedence over the global setting.

Default:(none) - The global setting applies.
Since:4.17

Size units

In the query parameters above, size can be specified in number of bytes as integer [ [ whitespace ] unit ] where the multiplier unit can be one of (case insensitive):

Unit Factor
KB 10001
K, KiB 210
MB 10002
M, MiB 220
GB 10003
G, GiB 230
TB 10004
T, TiB 240
PB 10005
P, PiB 250
EB 10006
E, EiB 260
ZB 10007
Z, ZiB 270
YB 10008
Y, YiB 280

It should be noted that currently, Vidispine has a 64-bit limit on the size of a storage, which means that multipliers larger than ZB are of limited use.
