zvault-algotest(1) -- Test a specific algorithm combination
|
|
===========================================================
|
|
|
|
## SYNOPSIS
|
|
|
|
`zvault algotest [OPTIONS] <FILE>`
|
|
|
|
|
|
## DESCRIPTION
|
|
|
|
This subcommand tests a specific combination of algorithms on a given input
|
|
`FILE`.
|
|
|
|
The subcommand exists to help users compare and select algorithms and
|
|
configuration options when creating a repository with _zvault-init(1)_ or
|
|
changing its configuration via _zvault-config(1)_.
|
|
|
|
The given algorithms will be used to simulate a backup run and determine the
|
|
efficiency and performance of each used algorithm as well as their combination.
|
|
|
|
The input file `FILE` is used as sample data during the test and should be
|
|
selected to be representative for the envisioned use case. Good examples of such
|
|
files can be tar files of system images or parts of a home folder.
|
|
Please note, that the input file is read into memory completely in order to
|
|
factor out the hard drive speed of the analysis.
|
|
|
|
The options are exactly the same as for _zvault-init(1)_.
|
|
|
|
|
|
## OPTIONS
|
|
|
|
* `--bundle-size <SIZE>`:
|
|
|
|

|
|
* `--chunker <CHUNKER>`:
|
|
|
|

|
Please see _zvault(1)_ for more information on *chunkers* and possible
|
|
values.
|
|
|
|
|
|
* `-c`, `--compression <COMPRESSION>`:
|
|
|
|
Set the compression method and level (default: brotli/3).
|
|
Please see _zvault(1)_ for more information on *compression* and possible
|
|
values.
|
|
|
|
|
|
* `-e`, `--encrypt`:

|
|
|
* `--hash <HASH>`:
|
|
|
|
Set the hash method (default: blake2).
