fsfreeze support + improved reporting + renew policy + checksumming + compression

[lephisto]

This includes the changes from the previous PR as well as the option, to renew the full backup every X Snapshots to increase safety on Backups. In the original version you would rely on never getting problems with your storage and a resilvering filesystem underneath.

Review would be nice.

Good. What do you think of moving fsfreeze from the hook script into the main script? If necessary we create a parameter --qemu-freeze

Best regards

[lephisto]

Yes sure, this could be done. Still, i'm working on making the restore function with the whiptail options compatible with the renew options..

[lephisto]

I added some more stuff. maybe you wanna look at it..

[franklupo]

In the next days i test fix Best regards

[franklupo]

Don't use eval but do_run(). This fiction support parametr dry-run for testing.--try-run and --debug is not documentate but show comand and no esecute

[franklupo]

Freeze work only qemu no Lxc. Filter execution only qemu.

[lephisto]

OK, will change this evening..

[franklupo]

How work import if compress backup?

[lephisto]

Restore w/ compression is still WIP.

[lephisto]

There's a ton of changes now.. restore with decompress / checksum validation is in now, i did some tests. Other testers welcome :)

[lephisto]

Ideas:

• Auto-Restore test (Test if Snapshots restore properly and fsck runs smooth)
• Fix Datehandling in Status routines
• Config Storage to get rid of clumsy commandlines.

Great ideas. But first I think it's worth testing this code and then releasing. It would be interesting to design tests to always check that everything is ok, If you agree, you could create a new TODO issue where all the ideas could be inserted.

Yes, feedback is much appreciated..
