Hi @Elune, welcome to the forum!
It sounds like you’re bringing up two different things here so let’s look at them individually:
The Restore list doesn’t include backups you expect to see
Without knowing your settings (are you running backups daily? do you have any retention policy rules that might be removing stale backups?) it’s hard to say what you SHOULD be seeing, so if you could include your job settings that could help (you can use the job “Export” → “As Command-line” menu then remove any passwords or personal info).
Another possibility is that possible there were no files changed / added / deleted on the days you think are missing (in your case May 10, 11, 12, 13, 14). Unless you have enabled the --upload-unchanged-backups parameter Duplicati doesn’t bother making a “backup” of no changes.
--upload-unchanged-backups
If no files have changed, Duplicati will not upload a backup set. If the backup data is used to verify that a backup was executed, this option will make Duplicati upload a backupset even if it is empty
Default value: “false”
If your job logs (or emails, if you use them) go back far enough you could check those for run times (meaning the backup ran) but 0 values in the following fields (meaning nothing changed):
DeletedFiles: 0
DeletedFolders: 0
ModifiedFiles: 0
…
OpenedFiles: 0
AddedFiles: 0
The Restore list of backups for “This week” includes days you don’t think it should
According to the post below, the time periods are rolling - so “This week” means “the last 7 days”, not “Monday through Sunday”, “Sunday through Saturday”, or whatever 7 day period your part of the world happens to consider a “week”.
