Git archive exports selected tracked content from a tree into a supported archive format. It can provide a clean source snapshot without a working directory’s incidental files. It does not automatically include repository history, uncommitted edits, external artifacts, or every dependency needed to build the project.
A dependable export defines the source identity and intended audience. This guide explains tree scope, attributes, dependencies, and validation so a convenient source archive is not mislabeled as a complete backup or an independently verified release artifact.
Choose the exact source tree
Select an approved commit, tag, or other supported tree reference deliberately. A branch name can move, so record the resolved source identity with the export when reproducibility matters.
Check the trust and approval status of that source through the team’s normal workflow. Running archive on a tag does not prove the tag was authorized or that its source passed acceptance tests.
Do not assume local uncommitted changes enter the archive. The export draws from the selected object state, not whatever happened to make a developer’s current working-tree build succeed.
Define the export’s intended use
A source distribution, review handoff, and disaster-recovery backup need different coverage. Name the purpose before choosing exclusions or calling the result complete.
If the recipient needs Git history and references, evaluate a repository-transfer mechanism rather than a tree-only archive. An extracted source directory cannot reconstruct every commit or review record.
Keep confidentiality scope explicit. A clean snapshot can still contain proprietary source, fixtures, or accidentally committed credentials. Review what is shared, not only the archive’s format.
Review export-ignore attributes
Files and directories marked with the supported export-ignore attribute can be omitted. This can exclude development-only content, but it can also remove something a recipient needs.
Inspect the attributes from the archived tree and any deliberately selected override behavior. A current working-tree attribute file is not automatically the source of every archive decision.
Test required files in the resulting archive. A successful command can produce an intentionally filtered tree that does not satisfy the build or handoff contract.
Keep export substitution controlled
Export-subst can expand supported placeholders in selected files. This can provide useful source metadata, but it means exported bytes can differ from the stored file content in the relevant way.
Document that transformation where byte identity matters. Do not compare an exported file hash to the original tree blob and declare corruption without accounting for deliberate substitution.
Keep substituted metadata nonsecret and minimal. A source distribution should not embed private operator information merely because a formatting placeholder can supply it.
Account for submodules and external artifacts
Submodule content belongs to separate repositories and needs a deliberate export or dependency workflow. The parent repository’s selected state does not automatically package every nested dependency.
Git LFS can represent large files through pointers while object content is managed separately. Verify the actual archive behavior and required artifact coverage through the approved tooling; do not assume every pointer becomes the binary payload.
Also review package registries, generated assets, and build tools. A tree snapshot can be correct while the project remains unrecoverable because an external dependency disappeared.
Choose format and path layout deliberately
Use a supported format and a clear prefix or path layout for the recipient. A predictable top-level directory can reduce accidental extraction into unrelated files, but extraction still needs its own safety controls.
Review permissions and metadata behavior for the chosen format and tools. A source file’s executable bit can matter for scripts. The recipient should test the resulting environment rather than assuming all platforms preserve identical semantics.
Avoid custom archive commands or remote formats without reviewing their execution and permission implications. Export convenience should not introduce uncontrolled shell behavior.
Bind the artifact to the approved release
Record the source identity and relevant export configuration in a protected manifest where the workflow requires it. A filename such as latest-source.zip does not identify the exact tree or attribute policy.
Use checksums for transfer integrity and the approved signing or provenance path for authenticity. A checksum delivered with an untrusted file does not by itself establish who authorized it.
Do not claim a source archive proves the deployed binary matches that source. Build inputs and transformations need separate artifact evidence.
Extract and test in a controlled environment
Inspect the archive and extract it into an isolated owned destination. Apply appropriate path, resource, and file-type protections. A Git-created archive still needs safe handling at the receiving boundary.
Verify representative files, required dependencies, and a supported build or acceptance test. Listing filenames is useful but not enough to prove the project operates from the exported snapshot.
Keep the test disconnected from unintended production actions. Build scripts and application startup can contact external services or execute hooks and tools under the recipient’s authority.
Maintain recovery coverage separately
If the export supports an ongoing release process, retain required versions and dependency information according to policy. Do not delete the only complete repository backup because source archives exist.
Periodically test an older retained export with its compatible build environment. Record limits when dependencies or external services no longer support restoration.
For a source handoff, archive an approved tree with reviewed attributes, provide explicit dependency instructions, and verify extraction and tests. The recipient receives a useful snapshot without an unsupported promise of full project history or recovery.
Review generated content and required fixtures
Export exclusions can remove tests or generated files that a recipient needs for the intended acceptance check. Decide which artifacts are intentionally regenerated and which must arrive with the source snapshot. Document that distinction beside the handoff rather than leaving the recipient to guess from a failed build.
Run the supported generation and tests from the extracted archive in a clean environment. This can reveal reliance on an untracked local file, a missing fixture, or an external tool not listed in the instructions. A correct source tree and a complete usable handoff are related but separate acceptance claims.
Frequently asked questions
Does Git archive contain uncommitted work?
Not automatically. It exports the selected tree state.
Is a source archive a complete repository backup?
No. History, references, and external dependencies need separate coverage.
Where are export attributes documented?
