How to create a backup archive in Borg?
Alternatively, give a reference file/directory. select compression algorithm, see the output of the “borg help compression” command for details. This command creates a backup archive containing all files found while recursively traversing all paths specified.
How to detect unmodified files in Borg create?
The detection of unmodified files is done by comparing multiple file metadata values with previous values kept in the files cache. This comparison can operate in different modes as given by –files-cache: Normally, detecting file modifications will take inode information into consideration to improve the reliability of file change detection.
Where does the Borg deduplicating archiver script run?
The following example script is meant to be run daily by the root user on different local machines. It backs up a machine’s important files (but not the complete operating system) to a repository ~/backup/main on a remote server. Some files which aren’t necessarily needed in this backup are excluded.
Where is the deduplication cache located in Borg?
Also, in order for the deduplication used by Borg to work, it needs to keep a local cache containing checksums of all file chunks already stored in the repository. This cache is stored in ~/.cache/borg/. If Borg detects that a repository has been modified since the local cache was updated it will need to rebuild the cache.
Is there a Borg command for copy of Repo?
There is no special borg command to do the copying, you could just use any reliable tool that creates an identical copy (cp, rsync, rclone might be options). But think about whether that is really what you want. If something goes wrong in repo, you will have the same issue in copy-of-repo.
Can you run Borg against multiple instances of the same Repo?
Also, you must not run borg against multiple instances of the same repo (like repo and copy-of-repo) as that would create severe issues: Data loss: they have the same repository ID, so the borg client will think they are identical and e.g. use the same local cache for them (which is an issue if they happen to be not the same).
Why does Borg always do full single-pass backups?
Borg always does full single-pass backups, so it will start again from the beginning – but it will be much faster, because some of the data was already stored into the repo (and is still referenced by the checkpoint archive), so it does not need to get transmitted and stored again.
