# bpfbak: a tiny tool to backup bpf objects under bpffs

Currently, bpffs does not support `cp` pinned bpf objects. This tool is a workaround to backup pinned bpf objects under bpffs.

## Usage

`bpfbak` can be used as a library:

```shell

    opts := bpfbak.BackupOpts{

        Src:            rootFlags.src,

        UnpinSrc:       rootFlags.srcUnpin,

        Dst:            rootFlags.dst,

        AutoMountBpffs: rootFlags.autoMount,

        BpffsPath:      rootFlags.mountBpffs,

    }

    err := bpfbak.Backup(opts)

    if err != nil {

        log.Fatalf("Failed to backup bpf object: %v", err)

    }

```

Or as a command line tool:

```shell

$ ./bpfbak -h

bpfbak is a tool to backup eBPF objects

Usage:

  bpfbak [flags]

Flags:

      --auto-mount           automatically mount bpffs at the destination directory or --mount-bpffs

  -d, --dst string           destination filepath to backup the bpf object

  -h, --help                 help for bpfbak

      --mount-bpffs string   path to the directory where bpffs is mounted

  -s, --src string           source bpf object to be backed up

      --unpin-src            unpin the source bpf object after backing up

```
