Data mobility
Data mobility is the ability to move files between storage systems, tiers, sites, and clouds on policy rather than as a project. It differs from a migration in that it is continuous and rule-driven. A catalog makes it safe because it decides which files qualify.
Key takeaways
- Moves follow rules, such as project, age, or owner, rather than one-time decisions.
- It is continuous and rule-driven, while a migration is a one-time project.
- The catalog keeps track of where each file now lives.
Why does data mobility matter?
Because the right place for data keeps changing. A project starts on fast storage, needs to reach a cloud service or an AI pipeline for processing, and ends on archive storage. Data mobility lets each move happen when the need appears, by rule, instead of waiting for a migration project. It also keeps an organization free to change storage vendors or clouds, because its data is not stuck where it was first written.
What is the difference between data mobility and data migration?
A migration is a one-time move, usually driven by a hardware refresh or a cloud adoption, with a start and an end. Mobility is an ongoing capability where files move whenever a rule says they should. A migration is a project. Mobility is an operating state.
What is the difference between data mobility and data movement?
Data movement is any act of copying or transferring data from one place to another, such as a file copy, a backup, or a step in a data pipeline. Data mobility is the ability to make those moves whenever they are needed, by rule, across storage systems, sites, and clouds, while the catalog keeps track of where each file now sits. Every mobility action involves data movement, but data movement on its own does not give an organization mobility.
What happens to the catalog when a file moves?
The catalog record follows the file. That is what keeps a move from breaking the estate view: the file is still described, still attributable to its project and owner, and still findable, with its new location recorded. A move that loses the description has traded one visibility problem for another.
How do you move data without breaking workflows?
Plan the move around the people and applications that use the data:
- Know who uses it, from owners and access dates, before anything moves.
- Move by rule and in stages, starting with data that is not in active use.
- Keep paths working or update them in the applications that depend on them.
- Keep the catalog current, so users can still find each file after it moves.
How does Diskover help?
Diskover moves files between systems, tiers, sites, and clouds on demand or by policy, from one catalog across every storage vendor.
