
Object names must comply with LTFS file naming rules:

The colon character (:) is not allowed in LTFS file names and
therefore not allowed in BlackPearl object names. The slash
character (/) is also technically not allowed in LTFS file names;
however, the BlackPearl software can accommodate a slash in
the object name and translates it as a directory in the LTFS file
system (e.g. directory1/directory2/video1.mov).

Directory names have a limit of 255 characters.

File names have a variable character limit. If you are using
English ASCII characters, the limit is 1024 characters. If you are
using a graphical language, such as Japanese, the limit is 512
characters.

Spectra Logic does not recommend the following characters in
LTFS file names or BlackPearl object names for reasons of cross ‐
platform compatibility: control characters such as carriage
return (CR) and line feed (LF), double quotation mark (“),
asterisk (*), question mark (?), less than sign (<), greater than
sign (>), backslash (\), forward slash (/) vertical line (|).

If you plan to eject tapes and read them in a non ‐ BlackPearl system,
Spectra Logic recommends that you set the Write Optimization setting
to Capacity when configuring a storage domain.

If you plan to eject tapes and read them in a non ‐ BlackPearl system,
Spectra Logic recommends that you enable Bucket Isolation when
configuring a data policy. This setting configures the bucket to have its
own unique set of tapes. This ensures that tape media containing one
bucket of information is not mixed with another bucket, making it
easier to restore data in a non ‐ BlackPearl system.

ERSIONING
If you plan to modify files on the Verde share that is configured for NFI
replication, you must configure the BlackPearl system with a storage
domain and data policy that allow versioning as described in this section.
If you do not plan to modify files on the Verde share, skip to Configure
Network File Interface on page 165 .
Once you create the required storage domain and data policy, you can then
either:

Create a bucket using the required data policy and specify that
bucket when configuring the NFI service.

Create a user and specify the required data policy as the default
data policy. Then when the NFI service creates a bucket specifying
that user as the owner, the bucket is created using the required data
policy.
