Tape Migration

If you are thinking about migrating all of your current tape libraries to one consolidated tape platform, get help from the experts at Ontrack. They can advise you about the steps that are required before carrying out this process.

Let the specialists at Ontrack take care of the job for you. We have established processes for every kind of tape-related service, and provide cost and time-effective conversion.

Simply put, you must restore your tape archives and then extract the data. Then you can either import the content into the new backup environment, after you recreated the archive structure, or if your new backup system allows it, you can copy or import the complete archives into the new data structure.

There are several options available to organisations  when it comes to dealing with upgrading your archive systems, each one with its own considerations. In any case, restoring and migrating an old archive structure which includes data is not an easy task. Each backup system has its own way of saving data in its tape library and onto the tapes themselves, so you must dig deep into the manuals in order to achieve a problem-free new backup environment.

Additionally, problems may arise when a client software is not available or if the paths to them have changed or are not working properly. This is often the case when only snapshots or dumps were taken instead of a full backup and the source consists of database files. In such a case, getting expert help is a better way of dealing with this issue. Our specialists have all the required knowledge and equipment for all the current and old software and hardware for tape and backup solutions. They use standardised processes for tape services, meaning that it is both time and cost-effective for you.

This depends on what you mean by a backup tape migration.

If you want to migrate your current backup files from one tape format to another, such as from LTO 2 to LTO 4, most backup software products have special commands implemented so you can perform this task quite easily without any major problems. In most cases, all you need is a tape drive in the new format to which you can copy the backup.

On a disk-to-disk backup approach, usually Virtual Tape Libraries (VTLs) are very useful. Backup software writes to virtual tape devices, like it would do with a real tape library, which is normally equipped with a mechanical tool and several physical tape devices. In addition every VTL has a unique internal structure and separate database, which stores contents inside the virtual tapes. From the outside, they look like large files with a totally different stream of data than how a tape disk dump (dd) may appear. What is even worse is that several VTLs also heavily duplicate the data that is written to them.

If you want to migrate these backup files that are currently stored on the VTL, there are functions implemented in most professional backup solutions to copy them back to the server or even to a second physical tape storage/library.

If you want to migrate your current backup files stored on tape from one backup software solution to another, this is not an easy thing to achieve successfully. If you are not familiar with the underlying structures of both software products involved, you will most likely end up exhausted and in the worst case scenario, left with a crashed backup system and no backups at all.

For a seamless and quick process, it is best to contact our tape data recovery service experts. We can advise you on the best course of action no matter what type of tape media you are using.

Changing or migrating your current backup software to a new backup software solution or product is not an easy task. You might say that executing some backup software commands that start a general restore from tapes to server can cause no problems. However, many of our clients have told us that the application always crashed doing when trying to do it. The backup software usually tries to recover files, entire servers and databases extremely fast, but it does not support a process of switching to different backup software.

Currently, there is only one product on the market that can help you migrate from TSM and NetBackup. However, for other backup software solutions there are no such applications available. Therefore, you have to do your migration job the traditional way: extract all the data stored in your current backup solution to an appropriate storage space; build the new backup system (both hardware and software) from scratch, create the archive architecture and import the new backup system. Additionally, all necessary clients, policy details and schedules, and tape inventories and catalogues have to be generated.

A task this bit can become overwhelming, even for an IT department in a large corporation, as it is very time-consuming. You should consider contacting a specialist tape migration service provider - make sure they have experience in successfully completing several migration projects for all kinds of enterprises, regardless of industry or size.

NetWorker is one of the most advanced backup storage solutions on the market. As with other solutions, the migration of an existing NetWorker system to another product is extremely problematic.

The best approach to such a project is to get access to the data stored inside NetWorker with the built-in recovery function. In doing so, the compressed NetWorker files will be extracted to another storage space from where you can import the data into the new system. Normally, it is nearly impossible to import the metadata managed by NetWorker into the new hardware and backup solution. In most cases, you have to build the metadata of the new system from scratch and import the content into the appropriate folders or archives. Furthermore, NetWorker has a lot of features integrated into the system which makes it - if problems arise during the migration process - difficult to recover the backup.

Whether the NetWorker backup system is based upon tapes or hard disks, or a combination of both, the integration of deduplication and virtualisation of backup files when recovering a NetWorker backup is a complicated task. Only specialised professionals can - if a backup is damaged - recover the backup and rescue the data inside. In such a case, we review the accessible data and search for references, which lead to the original structure of the underlying and compressed data files, whether they were stored in virtual machines or deduplicated for faster use and file size reduction.

In contrast to other backup storage software solutions, CommVault offers an easy way to migrate from other products. Its External Data Connector enables future or new clients of its current Simpana backup software to import the metadata which is stored inside a backup as well as details which are required regarding the current TSM, NetBackup or NetWorker storage structure, such as client information, policy details, job information, policy schedules, and tape inventories. With this information available, IT professionals then can translate the old clients to Simpana clients, deploy the client hardware and inherit the defined policies from the old TSM, NetBackup or NetWorker system.

In the unlikely event that migration doesn't work because of hardware or software failures, this can result in problems that even a talented IT administrator cannot solve by themselves. Broken tape library linkage or tape catalog files make it hard even for experts to recover the original structure of the entire backup system and the attached tape library. If a migration from TSM, NetBackup or NetWorker backup to CommVault stops midway through, then you can find yourself in deep trouble. In most cases, our experts can recover the data lost during the failed process and they can complete the migration.

You could import old NetBackup or NetWorker tapes to build a recent catalog, then either restore the data so you can access the content stored on tapes and disks and import it into Tivoli. Beforehand, you have to build the system from scratch, deploying all the policy domains, jobs, and structures. You can also try one of the special software solutions that are on the market, which can import NetBackup or NetWorker backups without the need for restoration. However, if this connector software doesn't work properly and the import fails, you will have even more problems.

If the original data structure - both the files inside the backup and the NetBackup or NetWorker policies, schedules and other solution data - is damaged by the process, it is hard to carry out a restore to the original state to begin the project again, or to make a traditional restore and import into TSM. In this case, our experts can both recover the lost data and migrate your old NetBackup or NetWorker system to TSM.
