Hello,
I am new Duplicacy user, looking to replace CrashPlan with it on my family computers. So far I am very happy with the program, it is amazingly fast and ingeniously designed. It has a bit steep learning curve though (compared to other programs like CrashPlan or Arc), but the forum offers a lot of useful information.
I am unsure about one thing, and that is proper use of the check command - obviously I want to keep my backups in a good shape, but the command has many options and I am not sure which one I should run regularly.
Currently my setup, made via the GUI, is like this:
- backups every 30 minutes
- maintenance every 2 hours with jobs in this order:
– check (local storage, no params)
– prune (local storage, 1:7 7:30 30:365 0:3650)
– copy (to remote storage)
– check (remote storage, no params)
– prune (remote storage, 1:7 7:30 30:365 0:3650)
Both storages are my Linux servers accessed via SFTP.
The question is, should I also run check command with some of the non default options? -files does not seem to be designed to run regularly since it downloads every single chunk for every snapshot. It is possible to specify a snapshot, but not with some vague option like “last”. -chunk does the same thing, but on chunk level rather than file level.
Also does the check actually solve problems on itself? Like if it finds a missing chunk, will it somehow cause the next backup run to fix the issue? Or should I watch the reports?
It appears to me that if I do no expect that something will mess with the filesystem of my SFTP storages, the plain check command is good enough to ensure the backups integrity, but I may be missing something thing.
Thank you.
