Enhancement: Simplify and improve restore performance
|
|
|
|
Significantly improves restore performance of large files (i.e. 50M+):

Fixes "not enough cache capacity" error during restore:
|
|
https://github.com/restic/restic/issues/2244
|
|
|
|
NOTE: This new implementation does not guarantee order in which blobs
|
|
are written to the target files and, for example, the last blob of a
|
|
file can be written to the file before any of the preceeding file blobs.
|
|
It is therefore possible to have gaps in the data written to the target
|
|
files if restore fails or interrupted by the user.
|
|
|
|
The implementation will try to preallocate space for the restored files
|
|
on the filesystem to prevent file fragmentation. This ensures good read
|
|
performance for large files, like for example VM images. If preallocating
|
|
space is not supported by the filesystem, then this step is silently skipped.
