basak / ddar Goto Github PK

I'm trying to build this on 16.04, and improvising as I go along, but I'm unable to get it to build successfully. Has anyone succeeded in building this on either 12.04/14.04/16.04?

I recently implemented wal-e for postgres, and it's s3 storage and restore are very compelling.

When/after porting over the old Synctus website (http://web.archive.org/web/20131209161307/http://www.synctus.com/ddar/) to GitHub (pages/wiki), it might be nice to add to the alternative list, and perhaps create comparisons pages for the main ones (like you before for tarsnap and rdiff-bacup).

I suppose these would include:

• ZBackup
• Attic
• Obnam
• ZPAQ
• Bup
• Burp
• Possibly others from this list: https://wiki.archlinux.org/index.php/backup_programs

What are your thoughts on this? With the proliferation of all these backup utilities and software lately, I personally think it would be of supreme helpfulness to have such a guide (summary and comparisons) on these various options, especially to the majority of people like me who aren't experts on this. Naturally you'd be a little biased towards your own software, but I hardly think that would undermine it as a tremendously useful resource. There's also the possibility of doing a simple comparisons matrix/table in addition or instead of the aforementioned.

Of course, this is a tacit request for you to do a fair amount of writing (and possibly research, depending on how much you already know about these alternatives). I hope I've convinced you it would be worth your while though. I could certainly help with this in some aspect, if you like.

Hey,

I am looking for an alternative to rdiff-backup.
It is not clear to me how you would do incremental backups with ddar. All the examples I've found seem to create an archive from scratch. Also appending seems to just add a file to an archive. How do I achieve the versioning offered by incremental backups?

For example:
Back up your home directory to an external disk daily:
tar c ~ | gzip --rsyncable | ddar cf /mnt/external_disk/home_backup

This reads like it just creates an archive and overwrites it the next day? Can I append with "-N home-2015-08-07" today and "-N home-2015-08-08" tomorrow to get two backups as seperate members but only have the diff between today and tomorrow take up space?

Also will I loose all my incremental backups if the archive with all these backups gets corrupted? How does this compare to the behavior of rdiff-backup in case of file corruption? Seems risky to have it all in one archive. I guess Rdiff-backup would at least give you backups up until the corrupted diff. But I know too little about rdiff-backup to make an informed decision. Also how likely is file corruption?

Thanks for your time. ddar looks like a great tool.

More specifically, I'm wondering (a) if you've thought about integrating the patch for Mac OS X support from #5 (b) tagging any releases? Indeed, (b) would allow me to write a Mac Homebrew formula for the software.

Any updates would be appreciated.

rsync supports RSYNC_RSH and "-e" to override the default of calling ssh. This allows an ssh alternative, as well as custom ssh parameters.

ddar should do the same thing, with parity to rsync to avoid user confusion.

I remember I used this great tool something like 4-5 years ago and it worked great back then, but now that I look at it it seems it hasn't been updated in a while.
As of today, would it make sense to use ddar in production?

Hi,

I'm interested in automatic encryption of the chunks using gpg. Is that possible with ddar?
