   --tempdir PATH, -t PATH  Temporary directory PATH (default: "/tmp")
   --target PATH            Target directory PATH to save backup archive (default: "./")
   --verbose, -v            Show process details

   --repos                  Backup repositories (default: true)

Currently seg-faults on dumping database. @lunny do you know why? 🙂

handle error

[lunny]

Any update @bkcsoft

[bkcsoft]

@lunny I'll see if I have time to look at this next week

[hoonetorg]

Regarding #2682:
When there will be a "gitea restore" command, there should be no reason to use zip iiac.
Also tgz can be handled fine in windows with a lot of programs afaik.

[bkcsoft]

Yeah, I agree that when we have gitea restore we could go for compressed tar-archives instead. Esp. since it's builtin to the language (instead of yet another dependency) https://golang.org/pkg/archive/tar/

[elvarb]

Will this be completed soon?

[lafriks]

@elvarb there is now other PR #2917

[elvarb]

@lafriks ok, glad to see lots of activity :)

[appleboy]

@bkcsoft conflicts.

[bkcsoft]

Closing this in favour of #2917
