Re: [Duplicity-talk] get rid of empty incremental changes

[Cláudio Gil]

I've also noticed those "empty" incremental files and looked for a way to remove them but, in the end, ~150 files (52 incremental backups) per year are fine for my case. My initial interest was more to keep it "clean" and with only the absolutely necessary files.

Adding the option may be useful. To me, at least, it seems as useful as --full-if-older-than. I guess a developer must comment how big a change it represents and someone needs to do it.

In terms of operations, duplicity always lists the files in the backend so it would save 3 uploads. Cloud storage is measured in cents per GB which makes the files essentially free to store when compared with a single picture.

Hi Cláudio,

Thanks, it seems that it could work just fine, checking the DeltaEntries stat.

But I wonder: am I the only one thinking that it is painful to produce these empty incremental changes ?

In my case, in a second step, I upload the incremental changes in the glacier. Uploading empty changes has a cost, and it clutters the directory with files, and I guess there is a (small) impact on performance.

Would not a ducplicity option controlling this behaviour prove useful ?

Best,

Karl

Hi,

I don't think there is a direct option that you can specify to avoid that. You could execute with --dry-run and check the statistics. If there are no changes then you can skip the backup.

Hello,

When performing an incremental backup, if there is no change, duplicity produces 3 files (the manifest, the difftar and the sigtar) that (as far as I understand) are useless.
I mean that if you delete them it does not change a thing, or I missed something.

Is there an easy way not to produce these empty backups, or to remove them ?

Thanks,

Karl Forner
