Therefore consolidation sessions, creating virtual full, do not copy the files hosting the data blocks, instead, the new session only refers to them by way of pointers. The new DFMF concept tries to reuse those files hence instead of copying the data blocks, they are only referred by way of pointers. If a consolidation session is performed on backups that are all located in the same File Library, the data that will be consolidated is already stored in one or more media files. This is done for each file, bigger than the used block size (default 64 KB) hence for each backed up file, a dedicated file on the File Library is created, which holds the data blocks. With the new media format, pure data blocks are written into different files. This is done per session hence each session creates its own file. Without this format HP Data Protector Software writes all data and catalog segments into one file. This format can only be used with the HP Data Protector software File Library and is by default not enabled. To improve speed of backup with Cloud replication HP Data Protector software 6.0 has a new media format is introduced, named distributed file media format (DFMF). For this reason a box to box replication scenario or a Data Protector replication configuration with a second copy of backup software at the remote site may be a more practical option. This limited functionality can be important if large files are uploaded which are modified daily (such as with synthetic backup used in backup software like HP Data Protector). Rather they are designed with specific functions called “put”, “get”, or “delete” for your files. However, be aware that some of these public cloud options are “block level” storage, meaning that uploaded files cannot be modified in place in the cloud. Options for this type of offsite replication can include box to box (where two Netswaps are configured at different locations to replicate from one to one another or bi-directionally) or to popular cloud options such as Amazon S3, Google Cloud Storage, DreamHost DreamCloud, and Dropbox. Ports must be open in the firewalls and Bandwidth must be available to deal with the large amount of data. Any Netswap can be configured to off-site data automatically over an Internet connection.
