"Solid [or TAR] archives are more sensitive to data damage. Unlike usual [non-solid] archives, all files after the damaged one [in the archive] most probably will also be damaged."

XZ/LZMA2 Format Inadequate For Long-Term Archiving. LZMA2 is unsafe and less efficient than the original LZMA. Use: 7Z LZMA Non-Solid, RAR 5 LZSS/PPMd Non-Solid, or ZIP Deflate.

RAR: "The 'Test archived files' option tests your archived files automatically and immediately after the archive is created. It ensures your data has been archived properly to disk."

RAR: "The Recovery Record is particularly useful for long-term backups. Optical media such as CD and DVD, flash memory like SSD/USB flash drives, and magnetic storage like HDD, can develop bad blocks after long-term storage. Optical media and flash memory are even more prone to data errors than HDDs.
Adding 5–10% Recovery Record to [archive file] backups intended for long-term storage provides additional protection against such errors. Adding the Recovery Record does not guarantee successful recovery, but does significantly increase the chances of recovering damaged data."

Manage modification of Archive Files like they're Solid: Decompress, Modify, Recompress.

"The data recovery company Ontrack did a study of the causes of data loss from 50,000 of its clients (1996). They found that the main causes were:
Hardware or System Malfunction (44% e.g. electrical failure, head/media crash, controller failure);
Human Error (32%);
Software Program Malfunction (14% e.g. corruption caused by diagnostic or repair tool, failed backups);
Malware (7%);
Natural Disasters (3%)"
