desync-cache - Read indexes and copy the referenced chunks

desync cache <index> [<index>...] [flags]

Read chunk IDs from one or more index files (caibx or caidx) and copy the referenced chunks from the source store(s) into the target store given with -c, without assembling any blob on disk. This can be used to pre-populate a cache, or to replicate the chunks referenced by indexes into another store. Use '-' to read (a single) index from STDIN.

To exclude chunks that are known to exist in the target store already, use --ignore <index> which will skip any chunks from the given index. The same can be achieved by providing the chunks in their ASCII representation in a text file with --ignore-chunks <file>.

--ca-cert="" trust authorities in this file, instead of OS trust store

-c, --cache="" target store the chunks are copied to

-r, --cache-repair[=true] replace invalid chunks in the cache from source

--client-cert="" path to client certificate for TLS authentication

--client-key="" path to client key for TLS authentication

-n, --concurrency=10 number of concurrent goroutines

-e, --error-retry=3 number of times to retry in case of network error

-b, --error-retry-base-interval=500ms initial retry delay, increases linearly with each subsequent attempt

-h, --help[=false] help for cache

--ignore=[] index(es) with chunks to be excluded

--ignore-chunks=[] text file with chunk IDs to be excluded

-s, --store=[] source store(s)

-t, --trust-insecure[=false] trust invalid certificates

--config="" config file (default $HOME/.config/desync/config.json)

--digest="sha512-256" digest algorithm, sha512-256 or sha256

--verbose[=false] verbose mode
