Enhancement: Restore files with long runs of zeros as sparse files
|
|
|
|
When using `restore --sparse`, the restorer may now write files containing long
|
|
runs of zeros as sparse files (also called files with holes), where the zeros
|
|
are not actually written to disk.
|
|
|
|
How much space is saved by writing sparse files depends on the operating
|
|
system, file system and the distribution of zeros in the file.
|
|
|
|
During backup restic still reads the whole file including sparse regions, but
|
|
with optimized processing speed of sparse regions.
