Best way to keep full backups without redundancy
Can and would someone please advise me? The situation: my hard drive is filling up due to my sloppy method of backing up ALL data from an Autoset A10. Regular antivirus scanning overworks the drive, takes far too long and slows down my W10 PC.
I have routinely copied from the SD card to my hard drive each night's set of two folders (DATALOG, SETTINGS) and three files (.crc, .tgt and .edf) generated by, or as updated by, the Autoset A 10 "last night". Oximetry data is embedded in those files as well. Each night of data is put into a new folder, i.e., last night's data is in the folder "170225" in my
CPAP folder. (I have noticed that the Autoset creates subfolders in the DATALOG folder that are named similarly, but it is no problem.)
Thinking I'd copy all to a jumpdrive and clear some storage space I found, duh, that there is, for a year and a half accumulation, at least a couple hundred gigabytes of files. My questions come down to two:
1. Isn't each daily (nightly) set of files indexed and self-referencing within itself so one cannot simply move a desired set of dated daily subfolders of the DATALOG folder, for a given sequence of nights into another date's DATALOG folder. I doubt one could see all such moved data upon downloading all to a blank SD card; it seems likely that necessary referencing and indexing would be absent.
2. Is the only way to preserve coverage, in view of a 30 day detailed data storage limit for SH or RS (as I recall), simply to retain, say, every 20th-25th daily folder, starting from the first one recorded and then deleting all 19-24 folders in between?--a scheme for preserving a means of reaching all days recorded...recognizing that one has to create a new patient name for each dataset (span of time) of interest.
Some past experience shuffling data:
I have found it necessary a time or two, for reasons forgotten, to erase the data card and download from storage older stored info, for its review, onto that emptied card. (I think the trouble I addressed was that in Sleepyhead or ResScan there were limits on how far back I could revisit Daily sleep records: summaries and detail.)

I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.
Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.
