Enhancement: Restore files with many 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): 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. We
|
|
have optimized the processing speed of sparse regions.
