Description
Default VERIFY
Job Priority
Low
When the storage domain receives a VERIFY job, it is
processed with low priority, which is the lowest
setting.
Note:
When using a Spectra S3 client, this setting can
be overridden when sending a VERIFY job by
specifying a different priority in the Create Verify Job
command. See the
Spectra BlackPearl Spectra S3 API
for more information.
Default Verify
After Write
cleared
Data is not verified after a write.
Rebuild Priority
Low
If data is lost from tape media, the data is rebuilt using
low priority, which is the lowest setting.
Checksum Type
MD5
Data using this storage domain is CRC checked using
the MD5 checksum type. Data is CRC checked when it
is written to cache with a PUT job, or read back from
media with a GET job.
End-to-end CRC
No
This data policy does not use end-to-end CRC
checking.
Versioning
None
In order to upload a new version of an object already
PUT to the system, the first version must be deleted.
Always Accept
Replicated PUT
Jobs
cleared
PUT jobs created for this data policy fail if one or more
replication targets the system must PUT to are
unavailable.
Data Persistence Rule for Tape First Copy
Type
Permanent
Data is moved to tape and maintained on tape media
until data is deleted from a bucket.
Note:
When data is deleted from a bucket, it is removed
from tape media, but individual tape media cartridges
are not reclaimed for use until all data is deleted from a
tape cartridge.
Bucket Isolation
Level
Standard
Data from different buckets can be mixed on to the
same piece of media.
