Hello,
I have a few questions that maybe someone will be so kind to answer. The first
question I believe I know the answer after reading through the BackupPC
documentation.
1. Am I correct in understanding that I must have compression enabled to take
advantage of the checksum caching option for full backups only, incremental
behavior does not change whether I have compressed or uncompressed files?
2. Would it be beneficial to enable compression solely to take advantage of
this feature? The reason I disabled compression is because most all data being
backed up is already compressed.
The documentation states:
Starting in 2.1.0, BackupPC supports optional checksum caching, which means the
block and file checksums only need to be computed once for each file. This
results in a significant performance improvement. This only works for
compressed pool files. It is enabled by adding'--checksum-seed=32761',
3. Lastly, this question may be a tough one or not possible at all. I love the
history option to view file versions, added, or removed from which backups. Is
there a way to grep this information from the command line or something to that
nature? With many level deep directories it can be difficult to discover these
changes such as when a file no longer exist in one backup compared to another.
Thank you for any help you may be able to provide!
