This commit adds support for specifying the `--host` option via the `RESTIC_HOST` environment variable. This is done by extending option processing in `cmd_backup.go` and for `restic.SnapshotFilter` in `find.go`.
On FreeBSD, limited users may not be able to even list xattrs for the
parent directories above the snapshot source paths. As this can cause
the backup to fail, just ignore those errors.
Two restic processes running concurrently can try to remove the same
files from the cache. This could cause one process to fail with an error
if the other one has already remove a file that the current process also
tries to delete.
In order to evaluate the keep reasons for snapshots, there should be also the id's
to compare it with snapshots within the keep object. (See also Issue #3117)
In order to avoid output parameters also changed function addJSONSnapshots to asJSONSnapshots
Other commands like key list and key remove show the key's ID.
Showing the ID here lets users easily reuse the ID as a key hint for subsequent
commands.
In particular, a key hint is needed when the repository has many keys - otherwise
opening the repository may fail with "Fatal: maximum number of keys reached" even
when a proper password is provided.
Fixes #4656
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
unlikely to be important
- find: filtered directories would be ignored. However, this
optimization missed that it is possible that two directories have the
exact same content. Such directories would be incorrectly ignored too.
Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```
Thus, remove the functionality as it's apparently too complex to use
correctly.
rclone returns a "not found" error if an internal error occurs while
listing a folder. Ignoring this error lets restic erroneously think that
there are no files, which can cause `prune` to wipe the whole
repository.
