A Veeam technology that points to blocks already on a volume rather than copying them, using features such as ReFS block cloning and XFS reflink, which makes synthetic fulls and transformations quicker and uses less space.

Terms in this definition
- Volume
Holds non-tabular files sitting in cloud storage under Unity Catalog governance, addressed as
/Volumes/<catalog>/<schema>/<volume>. A volume can be external or managed, andWRITE VOLUMEorREAD VOLUMEdecide who may use it. - Document Intelligence add-on capabilities
Extra Document Intelligence options switched on with the features query parameter: barcodes, formulas, keyValuePairs, languages, ocrHighResolution, queryFields and styleFont.
- ReFS
Resilient File System, aimed at large scale and data integrity: checksums, block cloning, mirror-accelerated parity and online repair with Storage Spaces. Windows cannot boot from it, and disk quotas and ODX, both found in NTFS, are missing.
- Block cloning
VHDX merges and file copies on ReFS run fast because clusters are remapped rather than data being read then rewritten.
- XFS
A Linux file system. Turn on reflink and Fast Clone becomes available to Linux and hardened repositories, speeding up the building of GFS points and synthetic full backups.
Related terms
- block reuse
Merges and synthetic fulls on object storage link to blocks the bucket already holds rather than uploading them afresh, so real consumption can come in under the logical size. Disk repositories get a similar saving from Fast Clone.
