Git Recovery Tools#

Git provides powerful tools for recovering lost work and maintaining repository health. Understanding these tools is crucial for handling complex recovery scenarios.

Key Tools#

            - •

                reflog:

                  Reference history tracking
            - •

                fsck:

                  File system check
            - •

                gc:

                  Garbage collection

Recovery Scenarios#

            - •

                Lost commits and branches
            - •

                Corrupted repositories
            - •

                Accidental overwrites

Using Git Reflog#

The reflog records updates to branch tips and other references, providing a safety net for recovering lost work.

Common Recovery Scenarios#

Recover from Bad Reset#

Restore Deleted Branch#

File System Check (fsck)#

Git fsck verifies the connectivity and validity of objects in your database, helping you find unreachable objects that might contain lost work.

Recovery Process#

            - 1.

Find Lost Objects#

            - 2.

Examine Content#

                `} variant="shell" />
            - 3.

Recover Objects#

                `}
                  variant="shell"
                />

Repository Maintenance#

Regular maintenance keeps your repository healthy and performs optimally. Understanding maintenance commands helps prevent issues before they occur.

Garbage Collection#

Repository Optimization#

Maintenance Schedule#

            - •

                Daily: git gc --auto
            - •

                Weekly: git repack -a -d
            - •

                Monthly: git gc --aggressive
