Veeam Backup & Replication ‚Fast Clone‘ – increases the speed of synthetic backup creation and transformation reduces disk space requirements and decreases the load on storage devices. With this technology, Veeam Backup & Replication references existing data blocks on volumes instead of copying data blocks between files. Data blocks are copied only when files are modified.
To configure a Linux backup repository for work with Fast Clone use the following XFS volume format string
# mkfs.xfs -b size=4096 -m reflink=1,crc=1 /dev/sda1
size=4096 sets file system block size to 4096 bytes
reflink=1 enables reflinking for the XFS instance (disabled by default)
crc=1 enables checksums, required for reflink=1 (enabled by default)
